Which of the following expressions contains exactly two terms?
quadratic |
|
polynomial |
|
monomial |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If the base of this triangle is 7 and the height is 4, what is the area?
| 70 | |
| 35 | |
| 52\(\frac{1}{2}\) | |
| 14 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 7 x 4 = \( \frac{28}{2} \) = 14
If angle a = 63° and angle b = 20° what is the length of angle c?
| 89° | |
| 91° | |
| 99° | |
| 97° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 63° - 20° = 97°
Which types of triangles will always have at least two sides of equal length?
isosceles and right |
|
equilateral and right |
|
equilateral, isosceles and right |
|
equilateral and isosceles |
An isosceles triangle has two sides of equal length. An equilateral triangle has three sides of equal length. In a right triangle, two sides meet at a right angle.
The dimensions of this trapezoid are a = 5, b = 2, c = 6, d = 8, and h = 3. What is the area?
| 15 | |
| 21 | |
| 17\(\frac{1}{2}\) | |
| 26 |
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(2 + 8)(3)
a = ½(10)(3)
a = ½(30) = \( \frac{30}{2} \)
a = 15
