The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
h2 x l2 x w2 |
|
h x l x w |
|
2lw x 2wh + 2lh |
|
lw x wh + lh |
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.
On this circle, line segment CD is the:
radius |
|
circumference |
|
chord |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
On this circle, a line segment connecting point A to point D is called:
circumference |
|
chord |
|
diameter |
|
radius |

Simplify (3a)(8ab) + (2a2)(2b).
| 28a2b | |
| 44ab2 | |
| -20ab2 | |
| 20ab2 |
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.
(3a)(8ab) + (2a2)(2b)
(3 x 8)(a x a x b) + (2 x 2)(a2 x b)
(24)(a1+1 x b) + (4)(a2b)
24a2b + 4a2b
28a2b
