BODMAS
division before addition
hence
28
{ 7[(3^2)-2(1+2)] / 7 } +5^2

The other people who answered this made a wrong assumption.
The way you have it written, the answer is:
7[9-6]/7 + 25
3 + 25
28
Is this one of your answer choices?

= 7([3 * 2] - 2[1 + 2]) / (7 + [5 *2])
= 7(6 - 2[3]) / (7 + 10)
= 7(6 - 6) / 17
= 7(0) / 17
= 0 / 17
= 0
Answer: 0
