What is 9a5 - 8a5?
| 17 | |
| 72a10 | |
| 1a5 | |
| 72a5 |
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.
9a5 - 8a5 = 1a5
Solve for y:
6y + 6 > \( \frac{y}{-5} \)
| y > 1\(\frac{1}{11}\) | |
| y > -2 | |
| y > -\(\frac{30}{31}\) | |
| y > 1\(\frac{1}{41}\) |
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.
6y + 6 > \( \frac{y}{-5} \)
-5 x (6y + 6) > y
(-5 x 6y) + (-5 x 6) > y
-30y - 30 > y
-30y - 30 - y > 0
-30y - y > 30
-31y > 30
y > \( \frac{30}{-31} \)
y > -\(\frac{30}{31}\)
A trapezoid is a quadrilateral with one set of __________ sides.
parallel |
|

A trapezoid is a quadrilateral with one set of parallel sides.
Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
factoring |
|
deconstructing |
|
squaring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
The dimensions of this cube are height (h) = 6, length (l) = 9, and width (w) = 4. What is the volume?
| 96 | |
| 216 | |
| 168 | |
| 126 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 9 x 4
v = 216
