I NEED HELP ASAP WITH THIS QUESTION.

a.) equivilent to;     4 x 7x - 4 x 6         and         28x-24

b.) equivilent to;     8y + 13y          and            21y

Step-by-step explanation:

A.)

4(7x-6)     First you have to multiply everything in the parenthesis by 4 because of distribution

7x x 4 - 6 x 4                That is why it is equivilent to the  4 x 7x - 4 x 6  awnser

28x - 24                    That is the end result by simplifiying and show why it is equivient to 28x-24

B.)

8y+6y+7y                 Simplify the like terms

8y+13y                   6+7 is 13 so that is why it is eauals to 8y+13y

21y                       if you continue adding you see why it equals 21y
