When 4 and a number n are multiplied, the result is 36: 4n = 36
Isolate the variable. Note the equal sign. What you do to one side, you do to the other. Divide 4 from both sides
(4n)/4 = (36)/4
n = 36/4
n = 9
9 is your answer for n

Given
![Area = 24200 yd^2](https://tex.z-dn.net/?f=Area%20%3D%2024200%20yd%5E2)
Required
Determine if the Perimeter is rational or not
First, we need to determine the sides of the square;
![Area = Length * Length](https://tex.z-dn.net/?f=Area%20%3D%20Length%20%2A%20Length)
Substitute ![Area = 24200 yd^2](https://tex.z-dn.net/?f=Area%20%3D%2024200%20yd%5E2)
![24200 = Length * Length](https://tex.z-dn.net/?f=24200%20%3D%20Length%20%2A%20Length)
![24200 = Length^2](https://tex.z-dn.net/?f=24200%20%3D%20Length%5E2)
Take Square root of both sides
![\sqrt{24200} = Length](https://tex.z-dn.net/?f=%5Csqrt%7B24200%7D%20%3D%20Length)
![Length = 155.563492](https://tex.z-dn.net/?f=Length%20%3D%20155.563492)
The perimeter of a square is calculated as:
![Perimeter = 4 * Length](https://tex.z-dn.net/?f=Perimeter%20%3D%204%20%2A%20Length)
![Perimeter = 4 * 155.563492](https://tex.z-dn.net/?f=Perimeter%20%3D%204%20%2A%20155.563492)
![Perimeter = 622.253968](https://tex.z-dn.net/?f=Perimeter%20%3D%20622.253968)
<em>Because the value of </em><em>perimeter </em><em>can't be gotten by dividing two integers, then </em><em>perimeter is irrational</em>
The answer would be 3x-4=2x+7 or D.
When you have a negative exponent, you move it to the other side of the fraction to make the exponent positive.
For example:
or ![\frac{x^{-2}}{1}=\frac{1}{x^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%5E%7B-2%7D%7D%7B1%7D%3D%5Cfrac%7B1%7D%7Bx%5E2%7D)
or y²
So:
![5^{-2}=\frac{1}{5^2}=\frac{1}{25}](https://tex.z-dn.net/?f=5%5E%7B-2%7D%3D%5Cfrac%7B1%7D%7B5%5E2%7D%3D%5Cfrac%7B1%7D%7B25%7D)
Your answer is B
