If a = c = 7, b = d = 6, what is the area of this rectangle?
| 8 | |
| 42 | |
| 16 | |
| 36 |
The area of a rectangle is equal to its length x width:
a = l x w
a = a x b
a = 7 x 6
a = 42
If a = -1 and y = 8, what is the value of 2a(a - y)?
| 18 | |
| 14 | |
| 192 | |
| -96 |
To solve this equation, replace the variables with the values given and then solve the now variable-free equation. (Remember order of operations, PEMDAS, Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.)
2a(a - y)
2(-1)(-1 - 8)
2(-1)(-9)
(-2)(-9)

On this circle, line segment AB is the:
chord |
|
radius |
|
diameter |
|
circumference |
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).
If a = c = 3, b = d = 1, and the blue angle = 68°, what is the area of this parallelogram?
| 48 | |
| 27 | |
| 4 | |
| 3 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 3 x 1
a = 3
A coordinate grid is composed of which of the following?
x-axis |
|
origin |
|
y-axis |
|
all of these |
The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.
