Question

Which algebraic expression is a product with a factor of 5

A) 3y+1

B)5(y-6)

C) -2y+5+3

D) 5y-7

Answer 1

B: Without expanding 5(y-6), you know that 5 is a factor because it's on the outside of the parenthesis.

Answer 2

For this case we have the following expression:

`5 (y-6)`

We observe that the number 5 is a common factor of both terms within the parenthesis.

To prove it, we can apply the distributive property.

We have then:

`5y - 30`

We observe then that 5 is a common factor of the given expression.

Answer:

An algebraic expression that is a product with a factor of 5 is:

B) 5 (y-6)
