Answer 1

The awnser to number 39. is a. 38 I say this because if you take 432 and divide it by 18 you get 24.
648÷27= 24
288÷12=24
so you then take 912 and divide it by 24

Answer 2

For questions 31 the answer is : 3y+5 Work: 3(y+4)-7 You distribute 3(y+4) which equals 3y+12 because you multipy. Now its : 3y+12-7 so, you subtract 12-7 which equals 5 . Your answer is now: 3y-5 · When disturbing you only multiply whats inside the perenteses (spelled wrong).
