The dimensions of this cube are height (h) = 4, length (l) = 1, and width (w) = 5. What is the surface area?
| 58 | |
| 80 | |
| 106 | |
| 192 |
The surface area of a cube is (2 x length x width) + (2 x width x height) + (2 x length x height):
sa = 2lw + 2wh + 2lh
sa = (2 x 1 x 5) + (2 x 5 x 4) + (2 x 1 x 4)
sa = (10) + (40) + (8)
sa = 58
If the base of this triangle is 2 and the height is 3, what is the area?
| 21 | |
| 112\(\frac{1}{2}\) | |
| 3 | |
| 12\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 2 x 3 = \( \frac{6}{2} \) = 3
If BD = 23 and AD = 29, AB = ?
| 6 | |
| 10 | |
| 1 | |
| 7 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDTo multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
Inside |
|
First |
|
Last |
|
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.
What is 6a + 5a?
| 11a | |
| 1 | |
| 30a | |
| a2 |
To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.
6a + 5a = 11a
