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 simplify expression
3(p)(2q) = 6pq

3(p)(2q) = 6pq is correct like Ms Sue confirmed for you
to check: you let p=2 and q=3
3(p)(2q) = 3(2)(6) = 36
6pq = 6(2)(3) = 36
since left side = right side, you had the right answer.
