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 angle a = 31° and angle b = 36° what is the length of angle c?
| 95° | |
| 113° | |
| 92° | |
| 91° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 31° - 36° = 113°
If side x = 10cm, side y = 10cm, and side z = 8cm what is the perimeter of this triangle?
| 31cm | |
| 26cm | |
| 40cm | |
| 28cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 10cm + 10cm + 8cm = 28cm
The dimensions of this cube are height (h) = 4, length (l) = 9, and width (w) = 9. What is the volume?
| 405 | |
| 12 | |
| 30 | |
| 324 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 9 x 9
v = 324
If the base of this triangle is 7 and the height is 2, what is the area?
| 52 | |
| 32\(\frac{1}{2}\) | |
| 38\(\frac{1}{2}\) | |
| 7 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 7 x 2 = \( \frac{14}{2} \) = 7
