Step-by-step explanation:

1. Remove the parenthesis using the next rules:

2. Start to remove the parentheses from the center to the edges:

<h2>Then, the solution is 8</h2>
Do your best remember volume is H+L+W and area is L*W
Just plug -3 where x is into the equation 2x^2 + 6 and solve
f(-3) = 2(-3)^2 + 6
f(-3) = 2(9) + 6
f(-3) = 18 + 6
f(-3) = 24
-2=-1/6(3)+b
-2=-0.5+b
-1.5+b
y=-1/6 -0.5
