Answer 1

Answer:

Distributive property

Step-by-step explanation:

see attached for reference

2 (x + 4)

= 2(x) + 2(4)

= 2x + 8

Answer 2

Answer:

Distributive property

Step-by-step explanation:

2 (x + 4) = 2 x + 8

In the equation the distributive property is used as the distributive property distributes a equation by taking common value from the equation.

In the the given equation 2 (x + 4), the 2 is multiplied individually to give 2 x + 8, Which can be reverse back to the previous equation by taking 2 as common from the equation.

The value of x can be find by equating the equation to zero

                              $2(x+4)=0$

                                $2x+8=0$

                                $2x= -8$

                                  $x=$$\frac{-8}{2}$

                                   $x= -4$
