The dimensions of this cube are height (h) = 2, length (l) = 1, and width (w) = 7. What is the volume?
| 48 | |
| 100 | |
| 70 | |
| 14 |
The volume of a cube is height x length x width:
v = h x l x w
v = 2 x 1 x 7
v = 14
Solve 2c + 5c = -3c - z - 5 for c in terms of z.
| -1\(\frac{1}{5}\)z - 1 | |
| z - \(\frac{3}{4}\) | |
| 15z + 4 | |
| -11z + 5 |
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
2c + 5z = -3c - z - 5
2c = -3c - z - 5 - 5z
2c + 3c = -z - 5 - 5z
5c = -6z - 5
c = \( \frac{-6z - 5}{5} \)
c = \( \frac{-6z}{5} \) + \( \frac{-5}{5} \)
c = -1\(\frac{1}{5}\)z - 1
Breaking apart a quadratic expression into a pair of binomials is called:
squaring |
|
deconstructing |
|
normalizing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The dimensions of this trapezoid are a = 4, b = 8, c = 7, d = 9, and h = 2. What is the area?
| 15 | |
| 22 | |
| 17 | |
| 45 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(8 + 9)(2)
a = ½(17)(2)
a = ½(34) = \( \frac{34}{2} \)
a = 17
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Last |
|
Inside |
|
Odd |
To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
