Answer:
15
Step-by-step explanation:
![\frac{25}{375} = \frac{1}{x}](https://tex.z-dn.net/?f=%5Cfrac%7B25%7D%7B375%7D%20%3D%20%5Cfrac%7B1%7D%7Bx%7D)
Cross multiply to get 25x = 375
Divide each side by 25 to get x = 15
I know there must be an equation to do this, but there is a simpler way.
Just factor number 72 into two numbers which, when multiplied, equal 72. Two of such numbers are 9 and 8, and you can see that the difference between those two numbers is just 1. So that is the answer to your question - the length of the patio is 9 feet, whereas the width is 8 feet.
Answer:
![\huge\boxed{slope=\dfrac{1}{2}=0.5}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7Bslope%3D%5Cdfrac%7B1%7D%7B2%7D%3D0.5%7D)
Step-by-step explanation:
The formula of a slope:
![m=\dfrac{y_2-y_1}{x_2-x_1}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7By_2-y_1%7D%7Bx_2-x_1%7D)
We have the points
![(-5;\ 3)\to x_1=-5;\ y_1=3\\(7;\ 9)\to x_2=7;\ y_2=9](https://tex.z-dn.net/?f=%28-5%3B%5C%203%29%5Cto%20x_1%3D-5%3B%5C%20y_1%3D3%5C%5C%287%3B%5C%209%29%5Cto%20x_2%3D7%3B%5C%20y_2%3D9)
Substitute:
![m=\dfrac{9-3}{7-(-5)}=\dfrac{6}{7+5}=\dfrac{6}{12}=\dfrac{6:6}{12:6}=\dfrac{1}{2}](https://tex.z-dn.net/?f=m%3D%5Cdfrac%7B9-3%7D%7B7-%28-5%29%7D%3D%5Cdfrac%7B6%7D%7B7%2B5%7D%3D%5Cdfrac%7B6%7D%7B12%7D%3D%5Cdfrac%7B6%3A6%7D%7B12%3A6%7D%3D%5Cdfrac%7B1%7D%7B2%7D)
The answer is going to be true
You have to give the problem and not just the options for me to solve
