To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Inside |
|
Last |
|
Odd |
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.
The dimensions of this trapezoid are a = 4, b = 4, c = 7, d = 4, and h = 2. What is the area?
| 32 | |
| 8 | |
| 10\(\frac{1}{2}\) | |
| 25 |
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(4 + 4)(2)
a = ½(8)(2)
a = ½(16) = \( \frac{16}{2} \)
a = 8
The endpoints of this line segment are at (-2, -4) and (2, 0). What is the slope of this line?
| -3 | |
| 1 | |
| 3 | |
| -2\(\frac{1}{2}\) |
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, -4) and (2, 0) so the slope becomes:
m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(0.0) - (-4.0)}{(2) - (-2)} \) = \( \frac{4}{4} \)Solve for y:
10y - 9 = -3 + 9y
| 1\(\frac{1}{8}\) | |
| 6 | |
| 1 | |
| \(\frac{5}{7}\) |
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 equal sign and the answer on the other.
10y - 9 = -3 + 9y
10y = -3 + 9y + 9
10y - 9y = -3 + 9
y = 6
