A right angle measures:
360° |
|
180° |
|
45° |
|
90° |
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.
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
squaring |
|
deconstructing |
|
normalizing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
Solve for c:
6c + 4 > -3 - 6c
| c > -\(\frac{1}{4}\) | |
| c > -1\(\frac{2}{5}\) | |
| c > -\(\frac{7}{12}\) | |
| c > -1\(\frac{1}{7}\) |
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.
6c + 4 > -3 - 6c
6c > -3 - 6c - 4
6c + 6c > -3 - 4
12c > -7
c > \( \frac{-7}{12} \)
c > -\(\frac{7}{12}\)
Which of the following expressions contains exactly two terms?
polynomial |
|
monomial |
|
binomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Odd |
|
Last |
|
First |
|
Inside |
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.
