Answer:
Add 36. The factored form is 
.
Step-by-step explanation:
A perfect square is a trinomial that factors into the form 
. To find the value to add to it divide 20 by 2 and square it.
12/2 = 6
6*6 = 36
This means c=36. The factored form is .
Looking at the question. you'll know that it's a subtraction question so that eliminates C and D. Now look at A and B. It says that 33 stamps were used. So that means the answer is not a negative expression. (B) Is Eliminated.
