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 the length of AB equals the length of BD, point B __________ this line segment.
bisects |
|
midpoints |
|
trisects |
|
intersects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
If c = -7 and x = 5, what is the value of c(c - x)?
| 84 | |
| 120 | |
| 135 | |
| 108 |
To solve this equation, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
c(c - x)
1(-7)(-7 - 5)
1(-7)(-12)
(-7)(-12)
84
If the base of this triangle is 8 and the height is 5, what is the area?
| 22\(\frac{1}{2}\) | |
| 60 | |
| 20 | |
| 36 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 8 x 5 = \( \frac{40}{2} \) = 20
The dimensions of this trapezoid are a = 5, b = 5, c = 7, d = 4, and h = 3. What is the area?
| 21 | |
| 12 | |
| 15 | |
| 13\(\frac{1}{2}\) |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(5 + 4)(3)
a = ½(9)(3)
a = ½(27) = \( \frac{27}{2} \)
a = 13\(\frac{1}{2}\)
