Simplify 4a x 9b.
| 36a2b2 | |
| 36ab | |
| 36\( \frac{a}{b} \) | |
| 13ab |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
4a x 9b = (4 x 9) (a x b) = 36ab
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
2lw x 2wh + 2lh |
|
lw x wh + lh |
|
h x l x w |
|
h2 x l2 x w2 |
A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.

If the base of this triangle is 6 and the height is 6, what is the area?
| 54 | |
| 18 | |
| 40 | |
| 66 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 6 x 6 = \( \frac{36}{2} \) = 18
