Answer:
4x+7/2
Explanation:
The Distributive property says that a(b+c) = ab+ac
In my example you distribute the value on the outside to the things on the inside
In your problem, you have a 1/2 on the outside that needs to be distributed to an 8x and 7
1) 1/2 multiplied by 8x equals 4x giving you the first part of your answer!
2) 1/2 multiplied by 7 equals 7/2 giving you the second part of your answer!
Don't forget that there is a + sign in between 8x and 7, don't drop it!
Put the two values together to get 4x+7/2
