Breaking apart a quadratic expression into a pair of binomials is called:
normalizing |
|
squaring |
|
deconstructing |
|
factoring |
To factor a quadratic expression, apply the FOIL (First, Outside, Inside, Last) method in reverse.
If the base of this triangle is 1 and the height is 2, what is the area?
| 42 | |
| 24 | |
| 1 | |
| 15 |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 1 x 2 = \( \frac{2}{2} \) = 1
A cylinder with a radius (r) and a height (h) has a surface area of:
π r2h |
|
4π r2 |
|
2(π r2) + 2π rh |
|
π r2h2 |
A cylinder is a solid figure with straight parallel sides and a circular or oval cross section with a radius (r) and a height (h). The volume of a cylinder is π r2h and the surface area is 2(π r2) + 2π rh.
Solve -8c - 2c = c + 7x + 5 for c in terms of x.
| -x - \(\frac{5}{9}\) | |
| -1\(\frac{1}{5}\)x - \(\frac{9}{10}\) | |
| -\(\frac{7}{10}\)x + \(\frac{1}{5}\) | |
| -1\(\frac{5}{6}\)x + \(\frac{1}{2}\) |
To solve this equation, isolate the variable for which you are solving (c) on one side of the equation and put everything else on the other side.
-8c - 2x = c + 7x + 5
-8c = c + 7x + 5 + 2x
-8c - c = 7x + 5 + 2x
-9c = 9x + 5
c = \( \frac{9x + 5}{-9} \)
c = \( \frac{9x}{-9} \) + \( \frac{5}{-9} \)
c = -x - \(\frac{5}{9}\)
If AD = 24 and BD = 21, AB = ?

The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BD
