Answer:
The first option: A.) For any numbers a, b, and c, a(b + c) = ab + ac.
Step-by-step explanation:
So anytime that you have a number or letter in front of a set of parenthesis that has numbers within (such as the example problem of: a(b + c)), you need to take the number outside of the parenthesis (a) in this situation) and multiply it to all of the numbers inside the parenthesis, like this:
a(b + c).
Multiply a into b, then multiply a into c, so that the equation looks like this:
ab + ac.
I hope that this helps.
