Answer:
D. 66/2
Explanation:
If you are trying to figure out what operation to perform first, then follow PEMDAS.
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
So first we start with what is in parenthesis. Since there are two operations within the parenthesis, we start with the division first since it comes first in PEMDAS. This is why D. 66/2 is our best answer.
