To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Last |
|
Odd |
|
Inside |
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 cube are height (h) = 6, length (l) = 9, and width (w) = 1. What is the volume?
| 54 | |
| 90 | |
| 162 | |
| 192 |
The volume of a cube is height x length x width:
v = h x l x w
v = 6 x 9 x 1
v = 54
Simplify 8a x 2b.
| 16\( \frac{b}{a} \) | |
| 16a2b2 | |
| 10ab | |
| 16ab |
To multiply monomials, multiply the coefficients (the numbers that come before the variables) of each term, add the exponents of like variables, and multiply the different variables together.
8a x 2b = (8 x 2) (a x b) = 16ab
If angle a = 35° and angle b = 20° what is the length of angle c?
| 114° | |
| 125° | |
| 91° | |
| 72° |
The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 35° - 20° = 125°
For this diagram, the Pythagorean theorem states that b2 = ?
c2 + a2 |
|
a2 - c2 |
|
c2 - a2 |
|
c - a |
The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)
