Question

Which expression is equivalent to 6m + (m – 2)(m + 7) + 3?

Answer 1

Answer: A. m^2+11m-11 on edge :)

Answer 2

Hello from MrBillDoesMath!

Answer:

m^2 + 11m - 11, which is the first choice

Discussion:

6m +  (m-2)(m+7) +3 =

6m  + (m^2 + 7m - 2m -14) + 3 =

(6m + 7m - 2m) + m^2 + (-14 + 3) =             combine similar terms

11m + m^2 -11 =

m^2 + 11m - 11

which is the first choice

Thank you,

MrB
