Question

Use the distributive property to rewrite the expressions.
-5/4(8a+4b)

Answer 1

`-(5)/(4) (8a+4b)=-10a-5b`.

Explanation:

1. Write the expression.

`-(5)/(4) (8a+4b)\\`

2. Apply the distributive property.

`(-(5)/(4) )(8a)+(-(5)/(4))(4b)\\ \\(-(5*8a)/(4)) +(-(5*4b)/(4)) \\ \\-(40a)/(4) -(20b)/(4)\\\\-10a-5b`

3. Express your result.

`-(5)/(4) (8a+4b)=-10a-5b`.
