Answer:
W = X in.
L = (3x - 6) in.
A = L*W = (3x-6)X = 45,
3x^2 - 6x = 45
3x(x-2) = 45,
x(x-2) = 15,
x^2 - 2x - 15 = 0
(x-5)(x+3) = 0,
x-5 = 0,
x = 5 in.
x+3 = 0,
x = -3.
Solution Set: x = 5, and x = -3.
Select + value of X:
x = 5
W = x = 5 in.
L = 3x-6 = 3*5 - 6 = 9 in.

Step-by-step explanation:
So, the point of this is to make x the only thing on one side, so we can see what x is!
Okay so first subtract 8 on both sides...
5x= 25
Now we need to divide on both sides!
That equals...
x=5
So now we know that x=5!
Hope this helped!! :D
