Breaking apart a quadratic expression into a pair of binomials is called:
deconstructing |
|
factoring |
|
squaring |
|
normalizing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
If a = 7, b = 7, c = 2, and d = 8, what is the perimeter of this quadrilateral?
| 19 | |
| 20 | |
| 18 | |
| 24 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 7 + 7 + 2 + 8
p = 24
If the length of AB equals the length of BD, point B __________ this line segment.
bisects |
|
intersects |
|
midpoints |
|
trisects |
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.
