Answer:
4 inches
Step-by-step explanation:
The equation for volume of a rectangular prism is V=lwh, where l=length, w=width, h=height.
We are given the volume, length, and width, so let's put those in and solve for the height.
V = lwh
660.24 = 13.1*12.6*h
660.24=165.06h
660.24/165.06 = h
4 = h
<u>The height is 4 inches.</u>

Answer:
The given equation is -2x^2 = -8x + 8
This can be rewritten as 2x^2 - 8x + 8 = 0
Here the value of a =2, b = -8 and c = 8
Discriminant = b^2 - 4ac
Now plug in the above values in the discriminant, we get
= (-8)^2 - 4*2*8
= 64 - 64
= 0
Here the discriminant is 0, so we will get one real root.
The discriminant is equal to 0, which means the equation has one real number solution.
Hope this will helpful.
Thank you.
