What is 5a - 3a?

80% Answer Correctly
8
15a
2a2
2a

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.

5a - 3a = 2a


2

If a = c = 6, b = d = 8, what is the area of this rectangle?

80% Answer Correctly
18
48
24
40

Solution

The area of a rectangle is equal to its length x width:

a = l x w
a = a x b
a = 6 x 8
a = 48


3

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

47% Answer Correctly

c2 - a2

c2 + a2

a2 - c2

c - a


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, \(c = \sqrt{a + b}\)


4

A coordinate grid is composed of which of the following?

91% Answer Correctly

x-axis

origin

all of these

y-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.


5

If the base of this triangle is 3 and the height is 6, what is the area?

59% Answer Correctly
9
42
38\(\frac{1}{2}\)
36

Solution

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

a = ½bh
a = ½ x 3 x 6 = \( \frac{18}{2} \) = 9
