Simplify 3a x 8b.
| 24\( \frac{a}{b} \) | |
| 24\( \frac{b}{a} \) | |
| 24a2b2 | |
| 24ab |
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 x 8b = (3 x 8) (a x b) = 24ab
On this circle, a line segment connecting point A to point D is called:
circumference |
|
diameter |
|
chord |
|
radius |
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).
The dimensions of this cube are height (h) = 6, length (l) = 3, and width (w) = 4. What is the volume?
| 72 | |
| 216 | |
| 16 | |
| 64 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 3 x 4
v = 72
The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?
lw x wh + lh |
|
h x l x w |
|
h2 x l2 x w2 |
|
2lw x 2wh + 2lh |
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 AB is the:

chord |
|
circumference |
|
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.
