A right angle measures:
90° |
|
45° |
|
360° |
|
180° |
A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
First |
|
Last |
|
Odd |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
If the base of this triangle is 2 and the height is 9, what is the area?
| 12\(\frac{1}{2}\) | |
| 60 | |
| 9 | |
| 50 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 2 x 9 = \( \frac{18}{2} \) = 9
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 |
|
h2 x l2 x w2 |
|
lw x wh + lh |
|
h x l x w |
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:
deconstructing |
|
factoring |
|
squaring |
|
normalizing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
