Breaking apart a quadratic expression into a pair of binomials is called:
deconstructing |
|
normalizing |
|
squaring |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
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 |
|
lw x wh + lh |
|
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.
What is 3a - 8a?
| -5 | |
| 11a2 | |
| 24a2 | |
| -5a |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
3a - 8a = -5a
A(n) __________ is to a parallelogram as a square is to a rectangle.
trapezoid |
|
rhombus |
|
triangle |
|

A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
If angle a = 35° and angle b = 57° what is the length of angle c?
| 90° | |
| 72° | |
| 104° | |
| 88° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 35° - 57° = 88°
