Simplify. (m + 13) - (p + 25)

A) m + 38
B) m + p - 12
C) –m + 13 - p
D) m – p – 12

D

Step-by-step explanation:

distribute the negative

m+13-p-25

combine like terms

m-p-12

.  Now the answers on your paper do not have this choice, but if you think about it, (2-x)=-1(x-2) and (1-x)=-1(x-1).  This means that when you have (2-x)/(1-x), this also equals to (x-2)/(x-1), since the -1's cancel out.  So, the answer is D.
