If BD = 5 and AD = 12, AB = ?
| 7 | |
| 5 | |
| 16 | |
| 20 |
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 cylinder are height (h) = 7 and radius (r) = 2. What is the volume?
| 28π | |
| 128π | |
| 9π | |
| 144π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(22 x 7)
v = 28π

What is 6a4 - 9a4?
| -3 | |
| -3a4 | |
| 54a8 | |
| 15a8 |
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.
