Answer:
7x + 70
Explanation:
As implied in the question, when you use the distributive property you need to distribute the factor outside the parenthesis to the ones inside the parenthesis.
When we look at 7(8+x+2)
You need to multiply all the factors inside the parenthesis by the 7 outside the parenthesis.
to break it down, do
7*8 = 56
7*x = 7x
7*2 = 14
From here, just add 56+14 to get 70 and then write out your answer as 7x + 70.
