Question

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

The sum of two constant factors seven and five plus a variable
The product of two constant factors seven and five plus a variable
The sum of a constant factor of five and a factor with the product of two terms
The product of a constant factor of seven and a factor with the sum of two terms

Answer 1

last one

Explanation:

Answer 2

Answer: LAST OPTION.

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.
