If a = 8, b = 7, c = 8, and d = 2, what is the perimeter of this quadrilateral?
| 25 | |
| 23 | |
| 12 | |
| 28 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 8 + 7 + 8 + 2
p = 25
Breaking apart a quadratic expression into a pair of binomials is called:
factoring |
|
squaring |
|
deconstructing |
|
normalizing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
Which of the following expressions contains exactly two terms?
quadratic |
|
monomial |
|
polynomial |
|
binomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
On this circle, line segment AB is the:
circumference |
|
chord |
|
radius |
|
diameter |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
Solve for z:
3z - 4 < \( \frac{z}{1} \)
| z < -\(\frac{45}{46}\) | |
| z < \(\frac{8}{13}\) | |
| z < 2 | |
| z < -3\(\frac{12}{17}\) |
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.
3z - 4 < \( \frac{z}{1} \)
1 x (3z - 4) < z
(1 x 3z) + (1 x -4) < z
3z - 4 < z
3z - 4 - z < 0
3z - z < 4
2z < 4
z < \( \frac{4}{2} \)
z < 2
