What is 3a + 6a?

80% Answer Correctly
-3a2
18a2
9
9a
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.

3a + 6a = 9a

2

If angle a = 24° and angle b = 65° what is the length of angle c?

70% Answer Correctly
100°
91°
60°
106°
Solution

The sum of the interior angles of a triangle is 180°:
180° = a° + b° + c°
c° = 180° - a° - b°
c° = 180° - 24° - 65° = 91°

3

A coordinate grid is composed of which of the following?

88% Answer Correctly

all of these

y-axis

origin

x-axis
Solution

The coordinate grid is composed of a horizontal x-axis and a vertical y-axis. The center of the grid, where the x-axis and y-axis meet, is called the origin.

4

Simplify (y + 4)(y + 8)

62% Answer Correctly
y2 + 4y - 32
y2 + 12y + 32
y2 - 12y + 32
y2 - 4y - 32
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:

(y + 4)(y + 8)
(y x y) + (y x 8) + (4 x y) + (4 x 8)
y2 + 8y + 4y + 32
y2 + 12y + 32

5

What is 3a6 - 9a6?

73% Answer Correctly
27a6
-6a6
12
12a12
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.

3a6 - 9a6 = -6a6
