Answer:
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
