The area of the walkway around is 26 x + 16 as the sum of two terms

Step-by-step explanation:

A rectangular garden has a walkway around it

1. The area of the garden is 4(4.5 x + 1.5)

2. The combined area of the garden and the walkway is 5.5(8 x + 4)

We need to find the area of the the walkway

To find the area of the walkway by subtracting the area of the

rectangle from the combined area

The combined area = 5.5(8 x + 4) ⇒ simplify it

The combined area = 5.5(8 x) + 5.5(4)

The combined area = 44 x + 22

The area of the garden = 4(4.5 x + 1.5) ⇒ simplify it

The area of the garden = 4(4.5 x) + 4(1.5)

The area of the garden = 18 x + 6

Now subtract the area of the garden from the combined area

Area of the walkway = (44 x + 22) - (18 x + 6)

Area of the walkway = 44x + 22 - 18 x - 6

- Add like terms

Area of the walkway = (44 x - 18 x) + (22 - 6)

Area of the walkway = 26 x + 16

Answer:

x=-1.16666666667 or x=-1.17

Step-by-step explanation:

2(4.5x+1.5) = 9x+3

2.5(6x+4) = 15x+10

9x+3=15x+10  subtract 3 on both sides

9x=15x+7 subtract 15x on both sides

-6x=7    divide -6 on sides

x=-1.16666666667 or x=-1.17

Answer:

We get -2 < r < 3

Corresponding to the fourth choice

The fourth number line is the correct option

Step-by-step explanation:

-2 < 3r+4 < 13

We have to isolate r,

subtracting 4 from each term,

-2-4< 3r + 4 - 4 < 13 - 4

-6 < 3r < 9

divding each term by 3,

-6/3 < r < 9/3

-2 < r < 3

so, the interval is (-2,3)

or, -2 < r < 3

this corresponds to

The fourth choice (since there is no equality sign)

Check below:

Step-by-step explanation:

To factorize the algebraic expression 3x² + 6x + 4x + 8, you can follow these three steps:

Step 1: Grouping

Group the terms in pairs so that you can factor out a common factor from each pair.

3x² + 6x + 4x + 8

(3x² + 6x) + (4x + 8)

Step 2: Factoring out the common factors

Factor out the common factors from each pair separately.

3x(x + 2) + 4(x + 2)

Step 3: Factoring out the common factor from the resulting expression

Notice that we have a common factor, (x + 2), in both terms.

(x + 2)(3x + 4)

Therefore, the factored form of the expression 3x² + 6x + 4x + 8 is (x + 2)(3x + 4).

Step-by-step explanation:

slope : ( The amount y increases , when x is increased by 1 )

slope : { y2 - y1 / x2 - x1 }

slope : y2 = 2

           y1 = -4

           x2 = 5

           x1 = 2

You must minus the values in the formula to find the slope line that passes through the points:

slope : { y2 - y1 / x2 - x1 }

slope : (2) - (-4) / (5) - (2)

=> 2 + 3 / 3

=> 6/3

=> 2

Text explanation:

Difference between both y-coordinates. = 6

Difference between both x-coordinates. = 3

Divide the difference between y and x. =

y/x =2

Which means the slope of the line that passes through the points (2,-4) and (5,2) is 2.

Hope this helps! Sorry it took so long! ⸜(｡˃ ᵕ ˂ )⸝ xx

The slope of the line that passes through the points (2, -4) and (5, 2) is 2.

A slope is also known as the gradient of a line is a number that helps to know both the direction and the steepness of the line.

slope = (y₂-y₁)/(x₂-x₁)

The slope of the line that passes through the points (2, -4) and (5, 2) can be calculated as shown below,

Slope = (y₂-y₁)/(x₂-x₁) =  [2 - (-4)] / (5 - 2)= 6/3 = 2

Hence, the slope of the line that passes through the points (2, -4) and (5, 2) is 2.

The equation of an arch for the given parabolic cross section is

y =  -2x² and its height is equal to 50 feet.

As given in the question,

Vertex of the parabola ( h , k ) = (0 , 0)

Focus is 0.5 foot below the given vertex.

Distance between focus and vertex 'a' = - 0.5

Standard equation of the parabola is given by:

( y - k ) = 4a ( x - h)²

Substitute the values we get,

( y - 0 ) = 4× (-0.5) ( x - 0)²

⇒ y = -2x²

Equation to represent the cross section of the given arch is

y = -2x²

Arch is 10 feet wide at ground level

⇒ x = 5 feet

Height of the arch is '( 0 - y)'

⇒ ( 0- y ) = 0 - 2(5)²

      = 50 feet

Therefore , the equation and height of the arch for the given parabolic cross section is equal to y =  -2x² and 50 feet respectively.

To begin solving this problem, we need to determine the dimensions of the rectangular region that the farmer will fence in. Let's say the length of thr uses, is given by the equation:
e rectangle is L and the width is W. The perimeter of the rectangle, which will be the length of fencing the farme
2L + W = 350

Solving for W, we get:

W = 350 - 2L

Next, we need to divide the rectangular region into three smaller rectangles by placing two parallel fences. Let's say the two fences are placed along the length of the rectangle, dividing it into three sections with widths of x, y, and z. Therefore, we have:

L = x + y + z

Now, we can determine the area of the entire fenced-in region by summing the areas of the three smaller rectangles. The area of a rectangle is given by the equation:

Area = Length x Width

Therefore, the total area of the fenced-in region is:

Area = (xW) + (yW) + (zW)

Substituting W = 350 - 2L and L = x + y + z, we get:

Area = (x(350-2(x+y+z))) + (y(350-2(x+y+z))) + (z(350-2(x+y+z)))

Simplifying this equation, we get:

Area = 350(x+y+z) - 2(x^2 + y^2 + z^2)

To maximize the area, we need to take the derivative of this equation with respect to one of the variables (x, y, or z), set it equal to zero, and solve for the variable. This process is too complicated to do by hand, so we will use a calculator or computer program to find the maximum area.

After finding the maximum area, we can determine the dimensions of the region that give us this maximum area. We do this by using the equations we derived earlier:

W = 350 - 2L

L = x + y + z

With the maximum area and these equations, we can solve for the dimensions of the region that give us the maximum area.

In summary, the farmer should fence in a rectangular region with dimensions that maximize the total area of three smaller rectangles created by placing two parallel fences. The maximum area can be found by taking the derivative of the area equation and setting it equal to zero. The dimensions of the region that give us the maximum area can be found by using the equations we derived earlier.

Therefore, general solution is ( 2nπ ± 2π/3 ), n ∈ Z⁺ .

One possible algorithm to find the largest subset of line segments in the plane where each pair of segments intersects is to sort the segments based on their x-coordinate of the endpoint on the line y = 1.

Then, use a sweeping line from left to right to keep track of the segments that are intersecting the line y = 0. When the sweeping line reaches the right endpoint of a segment, it can be removed from the set of intersecting segments.

The set of intersecting segments at any given time represents a candidate subset of segments that intersect each other. The size of the largest subset can be updated as the sweeping line moves to the right.

The running time of this algorithm is O(nlogn), as the sorting step takes O(nlogn) time and the sweeping line takes O(n) time to process each segment.

The proof of correctness follows from the observation that the set of intersecting segments at any given time during the sweeping process is a candidate for the largest subset.

Answer:

Hey there!

There are a total of 20 children, and 2+6, or 8 are girls.

Thus the probability of choosing a girl is 8/20, or 2/5.

There are 2 left handed girls, so the probability is 2/20, or 1/10.

Hope this helps :)

Answer:

see below

Step-by-step explanation:

There are 2+6 = 8 girls

P( girl) = number of girls/ total  = 8/20 = 2/5

P( left handed girl) = number of left handed girls/ total  = 2/20 = 1/10

Answer:

Penelope collected 43 quarters, 86 dimes, 344 nickels, and 129 pennies.

Step-by-step explanation:

From the problem statement, we know:

d = 2q (Twice as many dimes as quarters)

n = 4d (Four times as many nickels as dimes)

p = 3q (Three times as many pennies as quarters)

q + d + n + p = 780

q + 2q + 4d + 3q = 780

10q + 4d = 780

10q + 4(2q) = 780

18q = 780

q = 43.33 (rounded to two decimal places)

Since we can't have a fraction of a coin, we need to round down to the nearest whole number. Therefore, Penelope collected 43 quarters.

Using the other equations, we can then find the number of each type of coin:

d = 2q = 2(43) = 86 dimes

n = 4d = 4(86) = 344 nickels

p = 3q = 3(43) = 129 pennies

Answer:

Rise = 2

Run = 1

Slope = 2

Step-by-step explanation:

To find the rise you look at how much the line rises, so you can see it rises 2 after going over 1. So now we know the rise is 2 and the run is 1, because we used 1 as the run to find the rise.

The slope is found by dividing the run from the rise

\( \frac{rise}{run} \)

So the slope is 2.
