polynomial |
|
quadratic |
|
binomial |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
bisects |
|
intersects |
|
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.

A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
Solve for z:
-2z - 3 > 8 + 9z
| z > 1\(\frac{2}{5}\) | |
| z > -1 | |
| z > \(\frac{2}{3}\) | |
| z > 6 |
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.
-2z - 3 > 8 + 9z
-2z > 8 + 9z + 3
-2z - 9z > 8 + 3
-11z > 11
z > \( \frac{11}{-11} \)
z > -1
What is the circumference of a circle with a radius of 19?
| 36π | |
| 38π | |
| 8π | |
| 7π |
The formula for circumference is circle diameter x π. Circle diameter is 2 x radius:
c = πd
c = π(2 * r)
c = π(2 * 19)
c = 38π
