Which of the following expressions contains exactly two terms?
binomial |
|
polynomial |
|
quadratic |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If a = 7, b = 4, c = 8, and d = 2, what is the perimeter of this quadrilateral?
| 15 | |
| 22 | |
| 21 | |
| 19 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 7 + 4 + 8 + 2
p = 21
A trapezoid is a quadrilateral with one set of __________ sides.
parallel |
|
equal angle |
|
right angle |
|
equal length |
A trapezoid is a quadrilateral with one set of parallel sides.
Solve for c:
-7c + 6 > -3 - 3c
| c > -\(\frac{7}{9}\) | |
| c > 5 | |
| c > -\(\frac{4}{9}\) | |
| c > 2\(\frac{1}{4}\) |
To solve this equation, repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the > sign and the answer on the other.
-7c + 6 > -3 - 3c
-7c > -3 - 3c - 6
-7c + 3c > -3 - 6
-4c > -9
c > \( \frac{-9}{-4} \)
c > 2\(\frac{1}{4}\)
The dimensions of this cylinder are height (h) = 8 and radius (r) = 5. What is the volume?
| 252π | |
| 448π | |
| 200π | |
| 9π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(52 x 8)
v = 200π
