If AD = 21 and BD = 18, AB = ?

75% Answer Correctly
3
17
13
2
Solution

The entire length of this line is represented by AD which is AB + BD:

AD = AB + BD

Solving for AB:

AB = AD - BD
AB = 21 - 18
AB = 3

2

On this circle, line segment CD is the:

46% Answer Correctly

diameter

chord

circumference

radius
Solution

A circle is a figure in which each point around its perimeter is an equal distance from the center. The radius of a circle is the distance between the center and any point along its perimeter. A chord is a line segment that connects any two points along its perimeter. The diameter of a circle is the length of a chord that passes through the center of the circle and equals twice the circle's radius (2r).

The dimensions of this cube are height (h) = 6, length (l) = 3, and width (w) = 3. What is the volume?

82% Answer Correctly
70
20
54
63
Solution

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

v = h x l x w
v = 6 x 3 x 3
v = 54

4

If a = 5, b = 6, c = 8, and d = 1, what is the perimeter of this quadrilateral?

88% Answer Correctly
13
15
20
30
Solution

Perimeter is equal to the sum of the four sides:

p = a + b + c + d
p = 5 + 6 + 8 + 1
p = 20

What is 3a8 - 4a8?

73% Answer Correctly
-1a8
7a16
a816
12a16
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.

3a8 - 4a8 = -1a8
