Which expression represents the volume of the prism?

x(x – 2) cubic units
x(x +1) cubic units
x2(x – 2) cubic units
x2(x +1) cubic units

C. x∧2(x – 2) cubic units

Just took test.

x³-2x²  = x2(x – 2) cubic units

Step-by-step explanation:

The volume of a prism is found by multiplying the base area by the height. The base area is a parallelogram and so the area is x*(x-2) = x² -2x.

Multiply this area by the height x.

V = x(x² - 2x) = x³-2x²

This is the same as x2(x – 2) cubic units.

77

Step-by-step explanation:

the mean is the average, so if we add all the numbers, and divide it by the amount of numbers their are, we will get an average. In this case, we will add 76+79+80+82+50+78+83+79+81+82= 770. we have ten separate numbers we are adding together to get 770, so we divide 770 by ten to get our answer, 77.
