Question

How do you use the distributive property to rewrite and evaluate `(a+7)2`?

Answer 1

`2a + 14`

Explanation:

Distributive Property : `a(b + c) = ab + ac`

Here, The Expression can be written as :

`color(white)("XXX")` `(a + 7)2`
`=` `2(a + 7)` [Commutative Property: `a * b = b * a`]
`=` `2*a + 7 * 2` [Using the Distributive Property Here]
`=` `2a + 14`
