1

Which of the following expressions contains exactly two terms?

82% Answer Correctly

quadratic

monomial

binomial

polynomial


Solution

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


2

Solve 8b - 5b = 5b + 6x + 6 for b in terms of x.

34% Answer Correctly
3\(\frac{2}{3}\)x + 2
6x - 1
-\(\frac{1}{2}\)x + \(\frac{5}{6}\)
\(\frac{1}{10}\)x + \(\frac{4}{5}\)

Solution

To solve this equation, isolate the variable for which you are solving (b) on one side of the equation and put everything else on the other side.

8b - 5x = 5b + 6x + 6
8b = 5b + 6x + 6 + 5x
8b - 5b = 6x + 6 + 5x
3b = 11x + 6
b = \( \frac{11x + 6}{3} \)
b = \( \frac{11x}{3} \) + \( \frac{6}{3} \)
b = 3\(\frac{2}{3}\)x + 2


3

Simplify (6a)(6ab) - (4a2)(3b).

62% Answer Correctly
84a2b
48a2b
84ab2
24a2b

Solution

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.

(6a)(6ab) - (4a2)(3b)
(6 x 6)(a x a x b) - (4 x 3)(a2 x b)
(36)(a1+1 x b) - (12)(a2b)
36a2b - 12a2b
24a2b


4

For this diagram, the Pythagorean theorem states that b2 = ?

47% Answer Correctly

c2 + a2

c - a

c2 - a2

a2 - c2


Solution

The Pythagorean theorem defines the relationship between the side lengths of a right triangle. The length of the hypotenuse squared (c2) is equal to the sum of the two perpendicular sides squared (a2 + b2): c2 = a2 + b2 or, solved for c, \(c = \sqrt{a + b}\)


5

What is 3a4 - 3a4?

73% Answer Correctly
8
9a8
0a4
6

Solution

To combine like terms, add or subtract the coefficients (the numbers that come before the variables) of terms that have the same variable raised to the same exponent.

3a4 - 3a4 = 0a4
