I believe the correct answer is D)
could you show the picture up closer, so i can see?
≥-4
Pretend the greater than or equal to sign is an equal sign, we will substitute it back in later.
x/2 = -4
Multiply both sides by 2 to get x alone
x = -8
Substitute the greater than or equal to sign back in and voila!
x≥-8
if the length is 8ft and the width is (7+x) then the area would be 56+8x, if x is unknown.
I think the answer is D
Hope it helps
