correct reason for statement #2-C

            correct reason for statement #3-B  

             correct reason for statement #4-A

             correct reason for statement #5-D

Step-by-step explanation:

correct reason for statement #2-C

3(x+2)=3x+6 it is the distributive property

correct reason for statement #3-B

3x+6+1=3x+7 ,we are combining the like terms  i.e. we have combined the constant term and 3x has been left as it is

correct reason for statement #4-A

3x+7=8 ⇒ 3x=8-7=1 it is the subtraction property of equality since we are subtracting by 7 on both sides

correct reason for statement #5-D

3x=1  ⇒ x=1/3 it is division property of equality since we are dividing by 3 on both sides

hello :

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

the lenght is : 35 y^8

the width is : 15y^6
