Answer:
(4+5)3-8 = 19
Step-by-step explanation:
1) You know that the parenthesis are going to go around 3-8 or 4+5 because that is the only way multiplication is involved. If you put them anywhere else it doesn't change the answer.
2) Try solving the problems (use PEMDAS)
(4+5)3-8 = 9*3-8 = 27-8 = 19
4+5(3-8) = 4+5(-5) = 4-25 = -21
