I hope you don't find the solution too messy. If there is anything you don't get. Let me know and I will explain it:
Step-by-step explanation:
Answer:
n^2
Step-by-step explanation:
boom
you can only tak n^2
Add 2 to both sides
g + 2 = -2x
Divide both sides by -2
-g + 2/2 = x
Simplify g + 2/2 to 1 + g/2
-(1 + g/2) = x
Simplify brackets
-1 - g/2 = x
Switch sides
<u>x = -1 - g/2</u>
The answer is 8. <u>The mean is 8</u>
