Answer: 41 (i'm not really sure. but i was trying to help so please don't be mad

Step-by-step explanation:

8 * 4 = 32                           3 * 3 = 9 and 5 * 2 = 10

2 * 2 = 4                                         9 - 10 = -1                

32 + 4 = 36                                   -1 + 7 = 6 + 1 = 7

36 - 2 = 34

                                       34 + 7 = 41
