Answer :
The associative law states that it doesn't matter how we group numbers when we add and/or multiply. So we could rearrange the brackets and parentheses to get the equivalent equation:
9m(6+n)
Both equations total:
54m+9mn
(I applied the distributive property to solve it).
9m(6+n)
Both equations total:
54m+9mn
(I applied the distributive property to solve it).
