2l+2w=100
2(w+20)+2w=100
2w+40+2w=100
4w+40=100
4w=60
w=15
l=w+20
l=15+20
Greatest length is 35ft.

Step-by-step explanation:
The side of the square = x + 2, thus area is equal to
(x + 2)² ← expand using FOIL
= x² + 4x + 4
Given area = 7 then
x² + 4x + 4 = 7 ( subtract 4 from both sides )
x² + 4x = 3 ← as required

For this problem, you can start by taking the 35 and dividing it by 5 to get 7. Then you need to take 300 and divide that by 5 to get the right proportions. Then you can take your new number from 300 and divide that by 7, and you should not be on the right path because I'm probably an idiot.
Sorry bout it
Here's what I found !

"With an increase in temperature, the particles move faster as they gain kinetic energy, resulting in increased collision rates and an increased rate of diffusion. In a solid, the particles pack together as tightly as possible in a neat and ordered arrangement."</h2>

Answer:
D
Step-by-step explanation:
Divide the composite shape into 2 rectangles.
The dimensions of the 2 rectangles are :
Then, we plug in the values.
1st Rectangle
7 * (14 + 10)
7 * 24
168
2nd Rectangle
9 * 10
90
Then, we add together.
168 + 90 = 258
