Answer 1

Hi there! :)

Answer:

=28b-57

*The answer must have a positive sign.*

Explanation:

Lesson: Distributive property

Distributive property: a(b+c)=ab+ac

First, you expand or multiply by the numbers from left to right.

`7*7=49`

`7*4=28`

It change positive to negative sign.

`-49+28b-8`

Finally, you add/subtract by the numbers from left to right.

`49+8=57`

It change positive to negative sign.

`=28b-57`

Final answer is 28b-57

I hope this helps you!
