Question

Which of the following best describes the expression 7(y + 5)?

Answer 1

Answer: LAST OPTION.

Step-by-step explanation:

To solve this exercise is important to remember the following definitions:

1. The sum is the result obtained when we solve an addition.
2. The product is the result obtained when we solve a mutiplication.
3. Given a multiplication $(a)(b)=c$, "a" and "b" are factors and "c" is the product.

In this case, you have this expression:

$7(y + 5)$

Notice that the there is an addition of two terms ($y$ and $5$) inside the parentheses.

Outside the parentheses you can notice that the number $7$ is multiplying the sum of the terms  mentioned before.

Therefore, you can conclude that the best description for this expression is:

The product of a constant factor of seven and a factor with the sum of two terms.
