Add or subtract.(m? - m - 3) + (m-4)a. m^2 +m-1b. m^2+ 2m - 7c. m^2-7d. m^2 -1

C.

Step-by-step explanation:

(m^2-m-3) + (m-4)

there is no like terms for m^2 so it stays the stay.

next you add -m to m because the first m is negative they cancel out leaving nothing. lastly we add -4+-3 these added together give you -7.

so you are left with m^2 +0 -7

which simplifies to m^2 - 7

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time
