Answer:

 x = -6

Step-by-step explanation:

Step  1  :

Pulling out like terms :

1.1     Pull out like factors :

  -2x - 12  =   -2 • (x + 6)

Equation at the end of step  1  :

Step  2  :

Equations which are never true :

2.1      Solve :    -2   =  0

This equation has no solution.

A a non-zero constant never equals zero.

Solving a Single Variable Equation :

2.2      Solve  :    x+6 = 0

Subtract  6  from both sides of the equation :

                     x = -6

One solution was found :

                  x = -6

15 is what percent of 20
Lera25 [3.4K]
100%/x%=20/15
(100/X)*x=20/15*x   --I multiply both sides of the equation by X
100=1.33333333333*x --I divided both sides of the equation by                     .........................................(1.33333333333) to get X
100/1.33333333333=x
75=x
x=75

15 is 75% of 20

Answer:

g(h(- 8)) = 119

Step-by-step explanation:

Evaluate h(- 8), then substitute the result obtained into g(x), that is

h(- 8) = (- 8)² - 2 = 64 - 2 = 62, then

g(62) = 2(62) - 5 = 124 - 5 = 119
