Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
deconstructing |
|
squaring |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The dimensions of this cube are height (h) = 9, length (l) = 9, and width (w) = 6. What is the surface area?
| 182 | |
| 378 | |
| 94 | |
| 26 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 9 x 6) + (2 x 6 x 9) + (2 x 9 x 9)
sa = (108) + (108) + (162)
sa = 378

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
If a = 5, b = 8, c = 3, and d = 1, what is the perimeter of this quadrilateral?
| 17 | |
| 21 | |

| 20 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 5 + 8 + 3 + 1
p = 17
If the length of AB equals the length of BD, point B __________ this line segment.
trisects |
|
midpoints |
|
bisects |
|
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.
