Tim scored 35, 38, and 36 points on three tests. how many points should he get on the fourth test to get an average score of 40?

I think 51 because if you were to do it reverse then it would be 40x4=160 then -35-36-38 it would be 51.

The answer would be b ! explanation: the formula for sa *surface area * is 2×l×w+2×l×h+2×w×h so in this case l=4w=12h=8so you use the formula to solve it and it give you the answer of 352^cm^2

Ithink it’s d as the answer.
