area of rectangle = L x w
area = 8 sq ft
w= L-2
so 8 = L *L-2
8 = l^2-2l
l^2 -2l-8 = 0
(l-4) (l+2)=0
Length = 4 feet
Width = 2 feet

Answer:
x= −3 and y= 4
not sure if this is what your looking for tho
Step-by-step explanation:
If y+6=15, then y=9. (9+6)divided by 3 would be 5, not 15.
We are given that T = test score, and x = # of hours studied. We are given the same information in numbers:
T = 90
x = 6
y = ?
We need to figure out y in terms of k. Let's set up what we know:
Let's multiply both sides by y to get rid of it on the right side:
Now, let's divide by 90 on both sides to get rid of it from the left side (and solve for y):
Your answer is A! If any part didn't make sense, you know where to reach me.
