Simplify 5a x 8b.
| 40\( \frac{a}{b} \) | |
| 13ab | |
| 40a2b2 | |
| 40ab |
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.
5a x 8b = (5 x 8) (a x b) = 40ab
Breaking apart a quadratic expression into a pair of binomials is called:
deconstructing |
|
squaring |
|
factoring |
|
normalizing |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
On this circle, line segment AB is the:
diameter |
|
circumference |
|
chord |
|
radius |
A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).
To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?
First |
|
Last |
|
Inside |
|
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.
