Answer:

Step-by-step explanation:

(x + 5)2 + 2 = 42.5

x*2 + 5*2 + 2 = 42.5

  2x + 10 + 2 = 42.5

        2x + 12 = 42.5

               2x = 42.5 - 12

               2x = 30.5

                 x = 30.5/2

x = 15.25

Answer:

(x + 5)2 + 2 = 42.5

List of steps

2(x)+2(5)

2x+10

2x+10+2=42.5

2x+12=42.5

2x=42.5-12

2x=30.5

2x/2=30.5/2

x=30.5/2

x=15.25

x=15.25

Step-by-step explanation:

(x + 5)2 + 2 = 42.5

Solve (x+5)2 first

2(x)+2(5)

2x+10

Now the equation

2x+10+2=42.5

2x+12=42.5

Make 2x the subject

2x=42.5-12

2x=30.5

Divide both sides of the equation by 2

2x/2=30.5/2

x=30.5/2

x=15.25
