b.9m+4mn+(-12m)-7mn
c.2a²+3ab-7-5a²+2ab-4

Answer 1

-5a²+2a²+3ab+2ab-7-4= -3a²+5ab-11. maaf slh ngtng :v

Answer 2

A. 8p-3+(-3p)+8 = 8p-3p-3+8
=5p-5
5p= 5
p= 1
b. 9m+4mn+(-12m)-7mn
= 9m+(-12m)+4mn-7mn
= -3m-3mn
c. 2a²+3ab-7-5a²+2ab-4
= 2a²-5a²+3ab+2ab-7-4
= -3a²+5ab-11
mungkin itu jawabannya kalau nggak salah
