The answer is C
The reason: There are two width and two length sides. So, therefore, if you want the fencing to equal 40 feet around the perimeter, 8 · 2 + L · 2 has to = 40.
You would factor 2 out, and you get 2(8 + L) = 40.
Answer:
You must add 9/4 in order to make this a perfect square.
Step-by-step explanation:
To make any binomial into a perfect square trinomial, you have to take the middle term (-3), cut it in half (-3/2) and then square it (9/4). This will give you the constant to make a perfect square trinomial every time.
This problem can be solved with simple subtraction. 150.25 minus 78 will give you the answer you need. (72.25 yards of rope)

8 × 40 + 8 × 3
this is the expanded form
