The dimensions of this cube are height (h) = 5, length (l) = 3, and width (w) = 6. What is the volume?
| 6 | |
| 162 | |
| 90 | |
| 126 |
The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 3 x 6
v = 90
If the length of AB equals the length of BD, point B __________ this line segment.

A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
If a = c = 1, b = d = 6, and the blue angle = 60°, what is the area of this parallelogram?
| 56 | |
| 81 | |

| 6 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 1 x 6
a = 6

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.
(7a)(3ab) - (6a2)(8b)
(7 x 3)(a x a x b) - (6 x 8)(a2 x b)
(21)(a1+1 x b) - (48)(a2b)
21a2b - 48a2b
-27a2b
Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
deconstructing |
|
factoring |
|
squaring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
