Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
normalizing |
|
squaring |
|
deconstructing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
Which of the following expressions contains exactly two terms?
quadratic |
|
binomial |
|
monomial |
|
polynomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
A trapezoid is a quadrilateral with one set of __________ sides.
right angle |
|
equal length |
|
equal angle |
|
parallel |
A trapezoid is a quadrilateral with one set of parallel sides.
If angle a = 58° and angle b = 27° what is the length of angle c?
| 99° | |
| 60° | |
| 83° | |
| 95° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 58° - 27° = 95°
Solve for z:
-5z - 2 < 1 + 7z
| z < 1\(\frac{2}{5}\) | |
| z < -\(\frac{7}{8}\) | |
| z < -\(\frac{1}{4}\) | |
| z < \(\frac{8}{9}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the < sign and the answer on the other.
-5z - 2 < 1 + 7z
-5z < 1 + 7z + 2
-5z - 7z < 1 + 2
-12z < 3
z < \( \frac{3}{-12} \)
z < -\(\frac{1}{4}\)
