A quadrilateral is a shape with __________ sides.
2 |
|
4 |
|
3 |
|
5 |
A quadrilateral is a shape with four sides. The perimeter of a quadrilateral is the sum of the lengths of its four sides.
The dimensions of this cylinder are height (h) = 2 and radius (r) = 6. What is the volume?
| 6π | |
| 392π | |
| 324π | |
| 72π |
The volume of a cylinder is πr2h:
v = πr2h
v = π(62 x 2)
v = 72π
If a = 3, b = 9, c = 5, and d = 7, what is the perimeter of this quadrilateral?
| 29 | |
| 24 | |
| 22 | |
| 21 |
Perimeter is equal to the sum of the four sides:
p = a + b + c + d
p = 3 + 9 + 5 + 7
p = 24
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.
Solve for y:
-3y - 5 = \( \frac{y}{-5} \)
| -\(\frac{18}{19}\) | |
| \(\frac{18}{49}\) | |
| -1\(\frac{11}{14}\) | |
| -1\(\frac{2}{3}\) |
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 equal sign and the answer on the other.
-3y - 5 = \( \frac{y}{-5} \)
-5 x (-3y - 5) = y
(-5 x -3y) + (-5 x -5) = y
15y + 25 = y
15y + 25 - y = 0
15y - y = -25
14y = -25
y = \( \frac{-25}{14} \)
y = -1\(\frac{11}{14}\)
