Since a = 7, we need to plug in 7 for a.
2(7 + 8)
To solve for this, we need to use the distributive property. The distributive property allows us to multiply any number/variable outside of the parenthesis by all inside numbers/variables within the parenthesis.
It should look like this:
2(7) + 2(8).
Solve for each product.
2 x 7 = 14
2 x 8 = 16
We are now left with 14 + 16
14 + 16 = 30
30 is the value of the expression.
I hope this helps!
