Answer:
11, I know you got the answer, but just in case you need an explanation..
Explanation:
So, once you plug in the numbers it is... 3^2+3(8) divided by 2- 2(5). Then simplify the numbers... 9+24 divided by 2-2(5). Due to PEMDAS, division goes before addition or subtraction. So, 9+12-10. Simplify again ( it doesn't matter which property you use first..) Then 9+2 ( if you subtracted first ) and the final answer is 11.
