If AD = 13 and BD = 7, AB = ?
| 6 | |
| 16 | |
| 12 | |
| 1 |
The entire length of this line is represented by AD which is AB + BD:
AD = AB + BD
Solving for AB:AB = AD - BDWhich of the following statements about a triangle is not true?
exterior angle = sum of two adjacent interior angles |
|
area = ½bh |
|
sum of interior angles = 180° |
|
perimeter = sum of side lengths |
A triangle is a three-sided polygon. It has three interior angles that add up to 180° (a + b + c = 180°). An exterior angle of a triangle is equal to the sum of the two interior angles that are opposite (d = b + c). The perimeter of a triangle is equal to the sum of the lengths of its three sides, the height of a triangle is equal to the length from the base to the opposite vertex (angle) and the area equals one-half triangle base x height: a = ½ base x height.
Which of the following expressions contains exactly two terms?
polynomial |
|
quadratic |
|
binomial |
|
monomial |
A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.
If the base of this triangle is 6 and the height is 4, what is the area?
| 49\(\frac{1}{2}\) | |
| 66 | |
| 12 | |
| 32\(\frac{1}{2}\) |
The area of a triangle is equal to ½ base x height:
a = ½bh
a = ½ x 6 x 4 = \( \frac{24}{2} \) = 12
Solve for x:
2x - 2 > -4 + x
| x > -1 | |
| x > \(\frac{3}{5}\) | |
| x > -2 | |
| x > -\(\frac{4}{9}\) |
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 > sign and the answer on the other.
2x - 2 > -4 + x
2x > -4 + x + 2
2x - x > -4 + 2
x > -2
