Which of the following expressions contains exactly two terms?
binomial |
|
monomial |
|
quadratic |
|
polynomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
deconstructing |
|
normalizing |
|
squaring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
If side a = 5, side b = 3, what is the length of the hypotenuse of this right triangle?
| \( \sqrt{85} \) | |
| \( \sqrt{34} \) | |
| \( \sqrt{20} \) | |
| \( \sqrt{2} \) |
According to the Pythagorean theorem, the hypotenuse squared is equal to the sum of the two perpendicular sides squared:
c2 = a2 + b2
c2 = 52 + 32
c2 = 25 + 9
c2 = 34
c = \( \sqrt{34} \)
A(n) __________ is to a parallelogram as a square is to a rectangle.
rhombus |
|
triangle |
|

|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
The dimensions of this cylinder are height (h) = 5 and radius (r) = 2. What is the volume?
| 36π | |
| 72π | |
| 20π | |
| 12π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(22 x 5)
v = 20π
