To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.
This diagram represents two parallel lines with a transversal. If x° = 162, what is the value of b°?
| 36 | |
| 162 | |
| 154 | |
| 32 |
For parallel lines with a transversal, the following relationships apply:
Applying these relationships starting with x° = 162, the value of b° is 162.

A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
The endpoints of this line segment are at (-2, 0) and (2, -6). What is the slope-intercept equation for this line?
| y = -1\(\frac{1}{2}\)x - 3 | |
| y = 3x + 3 | |
| y = -\(\frac{1}{2}\)x - 1 | |
| y = \(\frac{1}{2}\)x - 3 |
The slope-intercept equation for a line is y = mx + b where m is the slope and b is the y-intercept of the line. From the graph, you can see that the y-intercept (the y-value from the point where the line crosses the y-axis) is -3. The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 0) and (2, -6) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-6.0) - (0.0)}{(2) - (-2)} \) = \( \frac{-6}{4} \)Plugging these values into the slope-intercept equation:
y = -1\(\frac{1}{2}\)x - 3
The dimensions of this trapezoid are a = 6, b = 5, c = 9, d = 4, and h = 5. What is the area?
| 32 | |
| 22\(\frac{1}{2}\) | |
| 30 | |
| 22 |
The area of a trapezoid is one-half the sum of the lengths of the parallel sides multiplied by the height:
a = ½(b + d)(h)
a = ½(5 + 4)(5)
a = ½(9)(5)
a = ½(45) = \( \frac{45}{2} \)
a = 22\(\frac{1}{2}\)
