The slope is 180 since that’s on the y-int.
5000, would be your answer.

Substitute for the value of x into the parenthesis;

ANSWER:
The expression equals 40 (when x = 3)
You need to go to school sorry I don’t know I just joined sorry
The area is given by
A = (5 + 2x) * (10 + 2x) - 50
Rewriting we have:
A = 50 + 10x + 20x + 4x ^ 2 -50
Rewriting we have:
A = 4x ^ 2 + 30x
Substituting the value of the area we have:
54 = 4x ^ 2 + 30x
Rewriting:
4x ^ 2 + 30x - 54 = 0
We look for the roots:
x1 = -9
x2 = 3/2
We take the positive root:
x2 = 3/2
Answer:
the value of x is:
x = 3/2
