If BD = 28 and AD = 29, AB = ?
| 1 | |
| 9 | |
| 20 | |
| 4 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDThe dimensions of this cube are height (h) = 4, length (l) = 7, and width (w) = 3. What is the volume?
| 180 | |
| 98 | |
| 84 | |
| 168 |
The volume of a cube is height x length x width:
v = h x l x w
v = 4 x 7 x 3
v = 84
Simplify 6a x 3b.
| 18\( \frac{a}{b} \) | |
| 18ab | |
| 18a2b2 | |
| 18\( \frac{b}{a} \) |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
6a x 3b = (6 x 3) (a x b) = 18ab
If a = 9, b = 2, c = 5, and d = 1, what is the perimeter of this quadrilateral?
| 25 | |
| 17 | |
| 22 | |
| 19 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 9 + 2 + 5 + 1
p = 17
