Four expressions are shown below:

4(8x + 2)
4(7x + 3)
32x + 8
28x + 12

Which two expressions are equivalent to 4(7x + 2 + x)?

Step-by-step explanation:

4(7x + 2 + x) = 4(8x + 2) = 4*8x + 4*2 = 32x + 8

4(7x + 2 + x) are equivalent to 4(8x + 2) and 32x + 8

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
