If a = c = 6, b = d = 5, and the blue angle = 73°, what is the area of this parallelogram?
| 24 | |
| 15 | |
| 35 | |
| 30 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 6 x 5
a = 30
Order the following types of angle from least number of degrees to most number of degrees.
right, obtuse, acute |

An acute angle measures less than 90°, a right angle measures 90°, and an obtuse angle measures more than 90°.
Solve 3b - 5b = 5b - 4z - 7 for b in terms of z.
| -\(\frac{1}{12}\)z - \(\frac{2}{3}\) | |
| -\(\frac{1}{2}\)z + 3\(\frac{1}{2}\) | |
| -\(\frac{1}{3}\)z - 2 | |
| z + \(\frac{1}{2}\) |
To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.
3b - 5z = 5b - 4z - 7
3b = 5b - 4z - 7 + 5z
3b - 5b = -4z - 7 + 5z
-2b = z - 7
b = \( \frac{z - 7}{-2} \)
b = \( \frac{z}{-2} \) + \( \frac{-7}{-2} \)
b = -\(\frac{1}{2}\)z + 3\(\frac{1}{2}\)
The dimensions of this cube are height (h) = 5, length (l) = 1, and width (w) = 2. What is the volume?
| 432 | |
| 12 | |

The volume of a cube is height x length x width:
v = h x l x w
v = 5 x 1 x 2
v = 10
If angle a = 62° and angle b = 57° what is the length of angle c?
| 114° | |
| 61° | |
| 96° | |
| 107° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 62° - 57° = 61°
