Answer:
The only one I can see right now is (C)
Step-by-step explanation:
Because a positive divided by a negative is negative, so 80/-10 is -8.
For A and B the numbers dont seem to make sense, are there any equations in middle of the numbers? I can help in comments if you tell me.

Step-by-step explanation:
The answer to each blank, in order from top to bottom
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
