Which expression is NOT equivalent to 2m 3 +4? A. 4 + 2m
B. 3m2+4
C. 2(m+2)
D. m+m2+3+1

I believe the answer is B,

explanation:

Well,  the others are exactly alike, the first answer is just the two numbers flipped, the third is where multiplication is needed, so (2 x m^3) + (2 x 2) = 2m^3 + 4. and the final one is m^3 plus itself which equals to 2m^3 + 4.

8+10
