The dimensions of this cube are height (h) = 1, length (l) = 1, and width (w) = 8. What is the volume?
| 64 | |
| 200 | |
| 8 | |
| 144 |
The volume of a cube is height x length x width:
v = h x l x w
v = 1 x 1 x 8
v = 8

| 9 | |
| 14 | |
| 5 | |
| 2 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD

A trapezoid is a quadrilateral with one set of parallel sides.
The dimensions of this cylinder are height (h) = 7 and radius (r) = 9. What is the volume?
| 405π | |
| 567π | |
| 32π | |
| 729π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(92 x 7)
v = 567π
Solve -2c + 5c = 8c - 8x + 5 for c in terms of x.
| \(\frac{9}{11}\)x - \(\frac{8}{11}\) | |
| -\(\frac{4}{13}\)x + \(\frac{1}{13}\) | |
| -\(\frac{1}{2}\)x + \(\frac{1}{2}\) | |
| 1\(\frac{3}{10}\)x - \(\frac{1}{2}\) |
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
-2c + 5x = 8c - 8x + 5
-2c = 8c - 8x + 5 - 5x
-2c - 8c = -8x + 5 - 5x
-10c = -13x + 5
c = \( \frac{-13x + 5}{-10} \)
c = \( \frac{-13x}{-10} \) + \( \frac{5}{-10} \)
c = 1\(\frac{3}{10}\)x - \(\frac{1}{2}\)
