Question

Shea wrote the expression 5(y+2)+4 to show the amount of money five friends paid for snacks at a baseball game.Which espression is equivalent to the one shea wrote?

Answer 1

Answer: B. 5 ∙ y + 5 ∙ 2 + 4

Explanation:

The options are:

a. 5 + y + 5 + 2 + 4

b. 5 ∙ y + 5 ∙ 2 + 4

c. 5 ∙ y + 5 ∙ 4 + 4

d. 5 ∙ y + 5 + 2 + 4

To solve the question, we have to expand 5(y+2)+4. This will be:

= (5 × y) + (5 × 2) + 4

= 5 ∙ y + 5 ∙ 2 + 4

= 5y + 10 + 4

= 5y + 14
