Answer 1

Hi there! :)

Answer:

=28b-57

*The answer must have a positive sign.*

Step-by-step 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!

Have a nice day! :)
