Breaking apart a quadratic expression into a pair of binomials is called:
squaring |
|
deconstructing |
|
normalizing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The dimensions of this cylinder are height (h) = 6 and radius (r) = 9. What is the volume?
| 24π | |
| 486π | |
| 16π | |
| 54π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(92 x 6)
v = 486π
A(n) __________ is to a parallelogram as a square is to a rectangle.
quadrilateral |
|
rhombus |
|
trapezoid |
|
triangle |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
If the base of this triangle is 3 and the height is 9, what is the area?
| 52\(\frac{1}{2}\) | |
| 84\(\frac{1}{2}\) | |
| 13\(\frac{1}{2}\) | |
| 39 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 3 x 9 = \( \frac{27}{2} \) = 13\(\frac{1}{2}\)
If side x = 15cm, side y = 14cm, and side z = 14cm what is the perimeter of this triangle?
| 35cm | |
| 32cm | |
| 24cm | |
| 43cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 15cm + 14cm + 14cm = 43cm
