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.
If the length of AB equals the length of BD, point B __________ this line segment.
intersects |
|
midpoints |
|
bisects |
|
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.
Order the following types of angle from least number of degrees to most number of degrees.
right, obtuse, acute |
|
acute, right, obtuse |
|
right, acute, obtuse |
|
acute, obtuse, right |
An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
Which of the following statements about a parallelogram is not true?
opposite sides and adjacent angles are equal |
|
the area of a parallelogram is base x height |
|
a parallelogram is a quadrilateral |
|
the perimeter of a parallelogram is the sum of the lengths of all sides |
A parallelogram is a quadrilateral with two sets of parallel sides. Opposite sides (a = c, b = d) and angles (red = red, blue = blue) are equal. The area of a parallelogram is base x height and the perimeter is the sum of the lengths of all sides (a + b + c + d).
Solve for c:
2c - 6 = \( \frac{c}{4} \)
| \(\frac{16}{71}\) | |
| 3\(\frac{3}{7}\) | |
| 1\(\frac{17}{19}\) | |
| -\(\frac{20}{21}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.
2c - 6 = \( \frac{c}{4} \)
4 x (2c - 6) = c
(4 x 2c) + (4 x -6) = c
8c - 24 = c
8c - 24 - c = 0
8c - c = 24
7c = 24
c = \( \frac{24}{7} \)
c = 3\(\frac{3}{7}\)
