Answer:
-9
Step-by-step explanation:
use P.E.M.D.A.S. to solve (Parenthese, Exponents, Multiplication, Division, Addition, Subtraction)
12(14/2)-3^3+15-9^2
first, divide 14 by two
(14/2)=7
12(7)-3^3+15-9^2
then, simplify your exponents
3^3=27 (3*3*3)
9^2=81 (9*9)
12(7)-27+15-81
next, multiply 12 by 7
12*7=84
84-27+15-81
Finally, go through and solve the subtraction/addition problems
84-27=57
57+15=72
72-81=-9
Hope this Helps!
