Perimeter of a rectangle is 2L+2W
let L=L
W= 2L-7
2L^2 - 7L = 100
Factor it at find that L= -5.53 or 9.03
Length can’t be a negative value si answer is 9.03 for length.
Plug this value in for W=2L-7
W=11.06
I’m pretty sure the answer would be “C” I’m not sure though

Question:
Yan is climbing down a ladder. Each time he descends 4 rungs on the ladder, he stopped to see how much farther he has to go. If Yan made eight stops with no extra steps, which expression best shows another way to write the product of the number of ladder rungs that Yan and climbed?
4+4+4+4
8+8+8+8
(-1)(4+4+4+4)
(-8) + (-8) + (-8) + (-8)
Answer:
Step-by-step explanation:
Given
<em></em>
<em> --- It is negative because he is climbing down</em>
![Steps = 8](https://tex.z-dn.net/?f=Steps%20%3D%208)
Required
An expression for the number of rungs climbed
To do this, we simply multiply the number of rungs by the steps taken.
![Total = Rungs * Steps](https://tex.z-dn.net/?f=Total%20%3D%20Rungs%20%2A%20Steps)
![Total = -4 * 8](https://tex.z-dn.net/?f=Total%20%3D%20-4%20%2A%208)
This can be rewritten as:
![Total = -8 * 4](https://tex.z-dn.net/?f=Total%20%3D%20-8%20%2A%204)
The product, when written as sum is:
I have no clue it's hard for me to even answer
