Which of the following expressions contains exactly two terms?
quadratic |
|
polynomial |
|
binomial |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If the base of this triangle is 5 and the height is 7, what is the area?
| 17\(\frac{1}{2}\) | |
| 84 | |
| 97\(\frac{1}{2}\) | |
| 105 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 5 x 7 = \( \frac{35}{2} \) = 17\(\frac{1}{2}\)
The dimensions of this cylinder are height (h) = 8 and radius (r) = 3. What is the volume?
| 729π | |
| 72π | |
| 81π | |
| 192π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(32 x 8)
v = 72π
Solve -2a + 3a = -3a + 5z + 5 for a in terms of z.
| 3z - 1 | |
| -\(\frac{1}{7}\)z + \(\frac{3}{7}\) | |
| z - 1\(\frac{2}{7}\) | |
| 2z + 5 |
To solve this equation, isolate the variable for which you are solving (a) on one side of the equation and put everything else on the other side.
-2a + 3z = -3a + 5z + 5
-2a = -3a + 5z + 5 - 3z
-2a + 3a = 5z + 5 - 3z
a = 2z + 5
