Answer:

The division will be represented as:

\(\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}\)

Step-by-step explanation:

1) Let's find a number with a variable that multiplied by 6x gives as 18x². It will be 3x, because (6x+5)3x=18x²+15x.

Now, let's subtstract:

\((18x^{2}-3x+4)-(18x^{2}+15x)=-18x+4\)

2) Let's find a number with a variable that multiplied by 6x gives as -18x. It will be -3, because (6x+5)(-3)=-18x-15.

Now, let's subtstract:

\((-18x+4)-(-18x-15)=19\)  

Therefore, the division will be represented as:

\(\frac{18x^{2}-3x+4}{6x+5}=(3x-3)+\frac{19}{6x+5}\)

Congruency shortcuts:  

HL, SSS, SAS, ASA, and AAS

where S=side

A=angle

H=hypotenule

L=leg

HL is only for a right triangle

If you can prove sides and angles are congruent according to those 5 rules, you have proven the triangles are congruent

Similarity shortcuts:

AA, SAS, SSS

We have triangle similarity if (1) two pairs of angles are congruent (AA) (2) two pairs of sides are proportional and the included angles are congruent (SAS), or (3) if three pairs of sides are proportional (SSS)

2)

BG ≅ GD              >Given from image

IG ≅ GO               >Given from image

<BGI ≅ <DGO        >Vertical Angles

ΔBGI  ≅ ΔDGO        >SAS            

You have proven that the triangles are congruent because you used the shortcut by proving a side and angle and a side are congruent so SAS makes them congruent

The polynomial functions of the given zeroes are:

5) f=x³+x²-10x+8

6) f=x³+4x²-15x-18

7) f=x²-x(1-i-7)+7i+7

8) f=x²-x(1-i)+2i+2

A function is said to as polynomial when a variable in an equation, such as a quadratic equation or cubic equation, etc., has only positive integer exponents or non-negative integer powers. One polynomial with an exponent of 1 is 2x+5, for instance. One that has more than two algebraic terms is referred to as a polynomial expression. Polynomial is a monomial or binomial that is repeatedly added, as the name suggests.

A mathematical expression containing one or more algebraic terms, where each algebraic term is made up of a constant multiplied by one or more variables raised to a nonnegative integral power.

5) The given zeroes are -4, 1, 2

(x+4)(x-1)(x-2)=0

x³+x²-10x+8=0

6) (x+6)(x+1)(x-3)=0

x³+4x²-15x-18=0

7) (x-7)(x-(1+i))=0

x²-x(1-i-7)+7i+7=0

8) (x-2i)(x-(1-i))=0

(x-2i)(x-1+i)=0

x²-x(1-i)+2i+2=0

By finding all the four slopes, we can see that the word is ECHA.

We know that the general linear equation can be written as:

y = a*x + b

Where a is the slope and b is the y-intercept.

We know that if the line passes through (x₁, y₁) and (x₂, y₂) then the slope is:

s = (y₂ - y₁)/(x₂ - x₁)

With that formula we can get the slopes.

1) Using the points (0, 3) and (2, 4).

m = (4 - 3)/(2 - 0) = 1/2, so the letter is E.

2)Using (-1, -12) and (1, -8)

m = (-8 + 12)/(1 + 1) = 4/2 = 2, so the letter is C.

3) We have (2, -6) and (-4, -3) so:

m = (-3 + 6)/(-4 - 2) = 3/-6 = -1/2, so the letter is H

4)we can use the points (0, 3) and (1, 1), so:

m = (1 - 3)/(1 - 0) = -2, so the letter is A

Then the word is ECHA

If line l is a perpendicular bisector of by the converse of the perpendicular bisector theorem.

Then,

AB = AC

Replacing

x+7.5 =3x-10.9

Solve for x

7.5+10.9 = -x+3x

18.4 = 2x

Change sides

2x = 18.4

x= 18.4/2

x = 9.2

Hence, the correct answer is x=9.2

The distance that Harold swim in 5 hours should be 16 km.

Given that,

Here we assume the distance be x

So,

\(6\frac{2}{5}\) =6.4

Now

\(\frac{6.4}{2}=\frac{X}{5}\)

2x=(6.4)(5)

2x=32

Now Divide by 2 on both sides  

Thus,  

X=16 km

Therefore, we can conclude that the distance that Harold swim in 5 hours should be 16 km.

The polygon has 21 sides whose interior angle are in Arithmetic Progression (A.P.)

The interior angles of a polygon are in an arithmetic progression (A.P) if the difference between any two consecutive angles is constant. To find the number of sides in a polygon given its smallest angle and the common difference of its interior angles, we can use the formula:

n = (180° - smallest angle) / common difference + 1, where n is the number of sides in the polygon.

In this case, the smallest angle is 100° and the common difference is 4°, so the number of sides can be calculated as follows:

n = (180° - 100°) / 4° + 1 = (80°) / 4° + 1 = 20 + 1 = 21.

Therefore, the polygon has 21 sides. It is important to note that a polygon with 21 sides is called an icosikaihenagon, which is a highly unusual and exotic shape, as most polygons have a smaller number of sides.

Step-by-step explanation:

Option C is correct.

We have the two following equation -

\(x^{2} +(6x^{2} +5)=5x^{2} -4\)

We have to find out which property justifies Gabrielle's first step.

According to associative property of addition changing the grouping of addends does not change the sum.

For example -  ( 2 + 3 ) + 4 = 2 + ( 3 + 4 )

According to the question, on the left hand side, we have -

\(x^{2} +(6x^{2} +5)\)

Using the associative property of Addition, we can write the above expression as -

\((x^{2} +6x^{2} ) + 5\)

which equals to :  \(7x^{2}\) + 5

Hence, option C is correct.

Answer: 48.8

Step-by-step explanation: The equation for the area of a circle is π*r², since the base of a cylinder is a circle we take the equation of a circle and multiply the height of the cynlinder by using the equation π*r²*h to get the volume of a cylinder. In this case our factors are

π= 3.14

r²= 6.76  

h=2.3

3.14*6.76*2.3=48.82072

rounded to the nearest tenth=48.8

I believe u have to factorise

(a+3)(a+5)

Answer:

Step-by-step explanation:

Let the first number be 'a' and the second number be 'b'. If the sum of the first and twice the second is 400 then;

a+2b = 400 ....

From the equation above, a = 400 - 2b ... 2

If the product of the numbers is a maximum then;

ab = (400-2b)b

let f(b) be the product of the function.

f(b) = (400-2b)b

f(b) = 400b-2b²

For the product to be at the maximum then f'(b) must be equal to zero i.e f'(b) = 0

f'(b)= 400-4b = 0

400-4b = 0

400 = 4b

b = 400/4

b = 100

Substituting b= 100 into the equation a = 400 - 2b to get a;

a = 400 - 2(100)

a = 400 - 200

a = 200

The two positive integers are 100 and 200.

The area of the triangle FGH is equal to  13√10 unit²

Given that the vertices;

F(-5,-7), G(-2,-5), and H(-6,-2)

We have to find the area of the triangle as;

Area of triangle = 1/2bh²

Here,

Area of triangle FGH = 1/2 (GH) (FG)²

Now,

Length of FG =  √26

Length of GH =  √10

Then,

Area of triangle FGH = 1/2 (GH) (FG)²

Area of triangle = 1/2 × √10 × √26²

Area of triangle = 1/2 × √10 × 26

Area of triangle FGH = 13√10

Therefore,

The area of the triangle FGH = 13√10 unit²
