Question

Which property can be used to expand the expression `-2(3/4x+7)`?

Answer 1

You can use the distributive property - see its application to this expression below

Explanation:

To use the distributive property you multiply the term outside the parenthesis (`color(red)(-2)`) by each term within the parenthesis to expand the expression:

`(color(red)(-2) xx 3/4x) + (color(red)(-2) xx7) ->`

`(-cancel(color(red)(2)) xx 3/(color(red)(cancel(color(black)(4)))2)x) + (color(red)(-2) xx7) ->`

`-3/2x + (-14) ->`

`-3/2x - 14`
