The dimensions of this cube are height (h) = 8, length (l) = 5, and width (w) = 7. What is the volume?
| 54 | |
| 280 | |
| 45 | |
| 126 |
The volume of a cube is height x length x width:
v = h x l x w
v = 8 x 5 x 7
v = 280
When two lines intersect, adjacent angles are __________ (they add up to 180°) and angles across from either other are __________ (they're equal).
acute, obtuse |
|
vertical, supplementary |
|
obtuse, acute |
|
supplementary, vertical |
Angles around a line add up to 180°. Angles around a point add up to 360°. When two lines intersect, adjacent angles are supplementary (they add up to 180°) and angles across from either other are vertical (they're equal).
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.
Breaking apart a quadratic expression into a pair of binomials is called:
squaring |
|
normalizing |
|
deconstructing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
If a = c = 7, b = d = 3, what is the area of this rectangle?
| 21 | |
| 10 | |
| 8 | |
| 6 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 7 x 3
a = 21
