Answer:
81m + 27t
Step-by-step explanation:
Using distributive property, this expression can be solved.
So 9(9m + 3t) has operations in it.
9 would be multiplied by whatever is in the parenthesis followed by the variable.
So 9 * 9 = 81.
9 * 3 = 27.
So putting it together with the variables.
It would be:
⇒ 81m + 27t
