1

Which of the following expressions contains exactly two terms?

82% Answer Correctly

quadratic

monomial

polynomial

binomial
Solution

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

2

A right angle measures:

90% Answer Correctly

45°

180°

360°

90°
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.

3

Solve for b:
b2 - 6b + 9 = 0

58% Answer Correctly
3
8 or -7
3 or -8
-3 or -5
Solution

The first step to solve a quadratic equation that's set to zero is to factor the quadratic equation:

b2 - 6b + 9 = 0
(b - 3)(b - 3) = 0

For this expression to be true, the left side of the expression must equal zero. Therefore, (b - 3) must equal zero:

If (b - 3) = 0, b must equal 3

So the solution is that b = 3

4

If a = 9, b = 8, c = 4, and d = 2, what is the perimeter of this quadrilateral?

88% Answer Correctly
19
16
23
20
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 9 + 8 + 4 + 2
p = 23

5

Which of the following statements about math operations is incorrect?

70% Answer Correctly

you can add monomials that have the same variable and the same exponent

you can subtract monomials that have the same variable and the same exponent

all of these statements are correct

you can multiply monomials that have different variables and different exponents
Solution

You can only add or subtract monomials that have the same variable and the same exponent. For example, 2a + 4a = 6a and 4a2 - a2 = 3a2 but 2a + 4b and 7a - 3b cannot be combined. However, you can multiply and divide monomials with unlike terms. For example, 2a x 6b = 12ab.
