Answer 1

I agree with you. When you multiply two negative numbers, the product is positive.

Answer 2

how would I check this on my own? I know you put numbers in the place of the letters but when I do that I come up with my moms answer. this is what i have when I check my work. p=-2 q=3
6*(-2)*3 =-36 but 3(-2)(-2*3)=36 could you tell me what i'm doing wrong when I check them pls

Answer 3

3(-p)*(-2q)=(-3p)*(-2q)= 6pq

Becouse product of two negative numbers is positive number.
