If a = c = 2, b = d = 3, and the blue angle = 64°, what is the area of this parallelogram?
| 7 | |
| 45 | |
| 4 | |
| 6 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 2 x 3
a = 6
If the length of AB equals the length of BD, point B __________ this line segment.
midpoints |
|
intersects |
|
bisects |
|
trisects |
A line segment is a portion of a line with a measurable length. The midpoint of a line segment is the point exactly halfway between the endpoints. The midpoint bisects (cuts in half) the line segment.
What is 2a8 + 2a8?
| 4 | |
| 4a16 | |
| a816 | |
| 4a8 |
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.
2a8 + 2a8 = 4a8
Which of the following expressions contains exactly two terms?
polynomial |
|
binomial |
|
monomial |
|
quadratic |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
Solve for y:
-2y - 6 < -8 + 4y
| y < \(\frac{1}{3}\) | |
| y < -\(\frac{1}{2}\) | |
| y < 1\(\frac{1}{3}\) | |
| y < \(\frac{5}{7}\) |
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.
-2y - 6 < -8 + 4y
-2y < -8 + 4y + 6
-2y - 4y < -8 + 6
-6y < -2
y < \( \frac{-2}{-6} \)
y < \(\frac{1}{3}\)
