Which of the following expressions contains exactly two terms?
polynomial |
|
binomial |
|
quadratic |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If side x = 8cm, side y = 8cm, and side z = 6cm what is the perimeter of this triangle?
| 25cm | |
| 21cm | |
| 29cm | |
| 22cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 8cm + 8cm + 6cm = 22cm
If angle a = 62° and angle b = 36° what is the length of angle c?
| 57° | |
| 84° | |
| 82° | |
| 123° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 62° - 36° = 82°
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
squaring |
|
normalizing |
|
deconstructing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
On this circle, line segment CD is the:
circumference |
|
radius |
|
diameter |
|
chord |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
