1

A right angle measures:

90% Answer Correctly

360°

90°

180°

45°
Solution

A right angle measures 90 degrees and is the intersection of two perpendicular lines. In diagrams, a right angle is indicated by a small box completing a square with the perpendicular lines.

2

If the base of this triangle is 1 and the height is 6, what is the area?

58% Answer Correctly
3
84\(\frac{1}{2}\)
77
60\(\frac{1}{2}\)
Solution

The area of a triangle is equal to ½ base x height:

a = ½bh
a = ½ x 1 x 6 = \( \frac{6}{2} \) = 3

3

Which of the following expressions contains exactly two terms?

81% Answer Correctly

monomial

quadratic

polynomial

binomial
Solution

A monomial contains one term, a binomial contains two terms, and a polynomial contains more than two terms.

4

If AD = 15 and BD = 13, AB = ?

75% Answer Correctly
2
1
8
11
Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 15 - 13
AB = 2

5

Factor y2 + y - 30

53% Answer Correctly
(y - 5)(y + 6)
(y + 5)(y + 6)
(y + 5)(y - 6)
(y - 5)(y - 6)
Solution

To factor a quadratic expression, apply the FOIL method (First, Outside, Inside, Last) in reverse. First, find the two Last terms that will multiply to produce -30 as well and sum (Inside, Outside) to equal 1. For this problem, those two numbers are -5 and 6. Then, plug these into a set of binomials using the square root of the First variable (y2):

y2 + y - 30
y2 + (-5 + 6)y + (-5 x 6)
(y - 5)(y + 6)
