Answer:
Volume = cubic inches
Step-by-step explanation:
A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.
We know,
Volume = area of base * height
THe base is a square and the area is side * side. We know each side is x, so we have:
Area of Square = Area of Base = x * x =
Now, we know height is also same side length, x, thus the volume becomes:
Volume = area of base * height
Volume =
We add the exponents when we have same base multiplied, so the expression for volume becomes:
Volume =
Answer:
f(-1) = 4
Step-by-step explanation:
See below for the synthetic division tableau. The remainder is 4, hence ...
f(-1) = 4
___
IMO, in this function it is far easier just to substitute -1 for x. Since the only terms are of even degree, the value of f(-1) is the sum of the coefficients:
f(-1) = -1 +1 +4
f(-1) = 4
