1

A(n) __________ is two expressions separated by an equal sign.

77% Answer Correctly

problem

formula

equation

expression
Solution

An equation is two expressions separated by an equal sign. The key to solving equations is to repeatedly do the same thing to both sides of the equation until the variable is isolated on one side of the equal sign and the answer on the other.

2

What is 4a7 + 4a7?

76% Answer Correctly
14
8a7
8a14
16a14
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.

4a7 + 4a7 = 8a7

3

The endpoints of this line segment are at (-2, 3) and (2, -3). What is the slope of this line?

46% Answer Correctly
\(\frac{1}{2}\)
-2
2
-1\(\frac{1}{2}\)
Solution

The slope of this line is the change in y divided by the change in x. The endpoints of this line segment are at (-2, 3) and (2, -3) so the slope becomes:

m = \( \frac{\Delta y}{\Delta x} \) = \( \frac{(-3.0) - (3.0)}{(2) - (-2)} \) = \( \frac{-6}{4} \)
m = -1\(\frac{1}{2}\)

4

To multiply binomials, use the FOIL method. Which of the following is not a part of the FOIL method?

84% Answer Correctly

First

Last

Odd

Inside
Solution

To multiply binomials, use the FOIL method. FOIL stands for First, Outside, Inside, Last and refers to the position of each term in the parentheses.

5

The dimensions of this cube are height (h) = 4, length (l) = 4, and width (w) = 2. What is the volume?

83% Answer Correctly
32
24
252
2
Solution

The volume of a cube is height x length x width:

v = h x l x w
v = 4 x 4 x 2
v = 32
