Help pls George is building a fence around a rectangular dog run. He is using his house as one side of the run. The area of the dog run will be 240 square feet. The length of the run is 30 feet, and the width is (30 minus x) feet. The diagram below shows his plan.
Recall the formulas for area and perimeter: A = lw and P = 2l + 2w.
The width of the dog run is 20 feet.
In the given problem, the length of the dog run is given as 30 feet.
The area of the dog run is also given as 240 square feet.
Using the formula for the area of a rectangle (A = lw), we can solve for the width (w).
Rearranging the formula, we have w = A / l.
Plugging in the values, we get w = 240 / 30 = 8 feet.
Since the width is given as (30 minus x) feet, we can set up an equation:
30 - x = 8. Solving for x, we find x = 22.
Therefore, the width of the dog run is 20 feet (30 - 22 = 8).
In this problem, the length and width of the dog run are defined by the dimensions of the fence being built around it.
The area of the dog run is given as 240 square feet.
By using the formula for the area of a rectangle, we can solve for the width. We are also given that the length is 30 feet.
Setting up an equation with the given width (30 minus x) and solving for x, we find that x is equal to 22.
This means that the width of the dog run is 8 feet. The main answer to the problem is that the width of the dog run is 20 feet (30 - 22 = 8).

A square garden has a length of (x+3) ft and a width of (x+2) ft. what is the perimeter and area of the garden?
Answer:
Perimeter:\(4x+10\) feet
Area:\(x^{2}+5x+6\) feet
Step-by-step explanation:
The perimeter is equal to 2*width +2*length. The width is x+2 and the length is x+3, therefore the perimeter is equal to 2x+4+2x+6 which equals 4x+10.
The area is equal to width*length
(x+3)(x+2)=\(x^{2}+2x+3x+6=x^{2}+5x+6\)

factorise x³-4x²+x+6
The binomial factors of x³- 4x²+x+6 are (x+2), (x+3), and (x-1).
Using the splitting and grouping the terms:
x³ + 4x² + x - 6
= x³ + 2x² + 2x² + x - 6 [Splitting 4x² = 2x² + 2x²]
= (x³ + 2x²) + (2x² + x - 6)
= x² (x + 2) + (2x² + 4x - 3x - 6)
= x² (x + 2) + [ 2x (x + 2) - 3 (x + 2)]
= x² (x + 2) + (x + 2) (2x - 3)
= (x + 2) ( x² + 2x - 3)
= (x + 2) ( x² + 3x - x - 3)
= (x + 2) [x (x + 3) - 1 (x + 3)]

A client would like this logo printed onto a canvas that is at least 70 inches tall. The original logo is 4.5 inches wide by 3.6 inches tall. Which of the following dimensions will keep the logo in proportion and large enough to meet the clients requirements?
Answer:
87.5 by 70 inches
Step-by-step explanation:
No options were given. So, I will calculate the minimum width
Given
\(Original\ Logo = 4.5 : 3.6\)
Height = 70 in ---- of the printed logo
Required
Determine the dimension that keeps the requirement
Let x be the width of the printed logo.
So, the ratio can be represented as:
\(Printed\ Logo = x : 70\)
Equate both ratios
\(x : 70 = 4.5 : 3.6\)
As fraction
\(x / 70 = 4.5 / 3.6\)
Multiply through by 70
\(70 * x / 70 = 4.5 / 3.6* 70\)
\(x = 87.5\)
So, one of the dimension that meets the requirement is a width of 87.5 inches

Differential Equation:
In mathematics, a differential equation is an equation relating one or more unknown functions to their derivatives. In applications, functions usually represent physical quantities, derivatives represent rates of change, and differential equations define the relationship between them. These relationships are common.
Now,
Given differential equation is

Part A: Find the total area of the brick paver border that surrounds the 12 ft by 32 ft pool. Show your work. (2 points) Part B: If brick pavers cost $8 per square foot, what is the total cost of the brick pavers needed for this project? Explain. (2 points)
Part A: The total area of the brick paver border is \(960\) square feet.
Part B: The total cost of the brick pavers needed for this project is $\(7,680\).
Part A: To find the total area of the brick paver border, we need to subtract the area of the pool from the area of the larger rectangle. The area of the pool is \(32\) feet multiplied by 12 feet, which is equal to \(384\)square feet.
The area of the larger rectangle is \(48\) feet multiplied by \(28\) feet, which is equal to \(1,344\) square feet. Therefore, the area of the brick paver border is \(1,344\) square feet minus \(384\) square feet, which equals \(960\) square feet.
Part B: If brick pavers cost $\(8\)per square foot, we can calculate the total cost by multiplying the cost per square foot by the total area of the brick paver border. The total area of the brick paver border is \(960\) square feet, and the cost per square foot is $\(8\).
Therefore, the total cost of the brick pavers needed for this project is $\(8\)multiplied by \(960\) square feet, which equals $\(7,680\).

a rectangle with a width of 30 centimeters has a perimiter of 100 centimeters to 160 centimeters graph a compound inequality
Answer:
5 ≤ L ≤ 35
Step-by-step explanation:
Let w represent the width of the rectangle.
The perimeter (P) of the rectangle is given by:
P = 2w + 2L
Where L is the length of the rectangle.
We know that w = 30 cm and that the perimeter is between 100 and 160 cm. We can now set up our compound inequality:
100 ≤ 2(30) + 2L ≤ 160
100 ≤ 90 + 2L ≤ 160
10 ≤ 2L ≤ 70
We can now divide both sides by 2 to solve for L:
5 ≤ L ≤ 35

\(2^{x^2 - 5x - 4} < 4\)
We have that 4 = 2², hence:
\(2^{x^2 - 5x - 4} < 2^2\)
As the exponential function is increasing over it's entire domain, the inequality can be represented as follows:
x² - 5x - 4 < 2
x² - 5x - 6 < 0.
The quadratic equation x² - 5x - 6 is concave up, hence it's negative between it's roots, obtained as follows:
(x - 2)(x - 3) = 0.
Applying the Factor Theorem:
x - 2 = 0 -> x = 2.x - 3 = 0 -> x = 3.Hence the solution to the inequality is of:
2 < x < 3.
The second inequality is given as follows:
\(\log_{0.3}{(x^2 + 3)} \geq \log_{0.3}{4x}\)
The logarithm function is also increasing over it's entire domain, hence the inequality is simplified as follows:
x² + 3 ≥ 4x
x² - 4x + 3 ≥ 0.
Another concave up quadratic equation, which is non-negative to the left of the smallest root and to the right of the highest root.
The roots are obtained by factoring as follows:>
(x - 3)(x - 1) = 0.
Hence:
x - 3 = 0 -> x = 3.x - 1 = 0 -> x = 1.Then the solution is given as follows:
x ≤ 1 or x ≥ 3.
