The answer is C because it is telling you to subtract 180 degrees from 54 degrees to get the final answer which is 126 I got that because 54 is that angle and it is asking for the whole amount so it would be C
3+2 = 5
80/5 =16
16 x 3 = 48
16 x 2 = 32
Answer= 48:32
I think this is right
-5x•(2x^2+x+3) is the answer
