Question

How do you simplify `(a + 7)2`?

Answer 1

`2a+14`

Explanation:

You use the Distributive Property. This property states that a constant (which, in this case, is `2`) multiplied by an expression in parentheses or brackets (this is the `a+7` part for your problem) is the constant multiplied by every term in the expression.

Put into math, the Distributive Property looks like this for your problem:

`(a+7)2`

`=a(2)+7(2)`

`=2a+14`

Answer 2

`(a+7)2=2a+14`

Explanation:

`(a+7)2`

Distribute the `2`.

`(2xxa)+(2xx7)`

Simplify.

`2a+14`
