A(n) __________ is to a parallelogram as a square is to a rectangle.
rhombus |
|
trapezoid |
|
triangle |
|
quadrilateral |
A rhombus is a parallelogram with four equal-length sides. A square is a rectangle with four equal-length sides.
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
deconstructing |
|
normalizing |
|
squaring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
What is the circumference of a circle with a radius of 5?
| 10π | |
| 14π | |
| 5π | |
| 20π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 5)
c = 10π
Solve for y:
-8y + 6 < \( \frac{y}{-9} \)
| y < 3\(\frac{3}{11}\) | |
| y < \(\frac{54}{71}\) | |
| y < 3\(\frac{7}{11}\) | |
| y < 14 |
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 < sign and the answer on the other.
-8y + 6 < \( \frac{y}{-9} \)
-9 x (-8y + 6) < y
(-9 x -8y) + (-9 x 6) < y
72y - 54 < y
72y - 54 - y < 0
72y - y < 54
71y < 54
y < \( \frac{54}{71} \)
y < \(\frac{54}{71}\)
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.
