Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
deconstructing |
|
squaring |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
If a = c = 6, b = d = 8, and the blue angle = 50°, what is the area of this parallelogram?
| 35 | |
| 4 | |
| 12 | |
| 48 |
The area of a parallelogram is equal to its length x width:
a = l x w
a = a x b
a = 6 x 8
a = 48
Simplify 8a x 2b.
| 16ab | |
| 16a2b2 | |
| 16\( \frac{a}{b} \) | |
| 16\( \frac{b}{a} \) |
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 side x = 13cm, side y = 13cm, and side z = 11cm what is the perimeter of this triangle?
| 31cm | |
| 37cm | |
| 34cm | |
| 24cm |
The perimeter of a triangle is the sum of the lengths of its sides:
p = x + y + z
p = 13cm + 13cm + 11cm = 37cm
Order the following types of angle from least number of degrees to most number of degrees.
