3 (5+6)

Distributive property

Answer: 33

Step-by-step explanation: The distributive property tells us that when there's a number outside a set of parentheses, you can multiply it times each of the terms that are inside the set of parentheses and then add those products together.

So in this problem,

we can multiply 3 (5) + 3 (6) which simplifies to 15 + 18 which equals 33.

15+18=33

33 is the answer
