What is 4a - 5a?

80% Answer Correctly
-a2
20a2
a2
-1a
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.

4a - 5a = -1a

2

The formula for volume of a cube in terms of height (h), length (l), and width (w) is which of the following?

67% Answer Correctly

2lw x 2wh + 2lh

lw x wh + lh

h x l x w

h2 x l2 x w2
Solution

A cube is a rectangular solid box with a height (h), length (l), and width (w). The volume is h x l x w and the surface area is 2lw x 2wh + 2lh.

3

If BD = 16 and AD = 22, AB = ?

76% Answer Correctly
13
6
5
12
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 = 22 - 16
AB = 6

4

The dimensions of this cube are height (h) = 8, length (l) = 9, and width (w) = 3. What is the volume?

83% Answer Correctly
36
56
216
252
Solution

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

v = h x l x w
v = 8 x 9 x 3
v = 216

When two lines intersect, adjacent angles are __________ (they add up to 180°) and angles across from either other are __________ (they're equal).

60% Answer Correctly

obtuse, acute

supplementary, vertical

vertical, supplementary

acute, obtuse
Solution

Angles around a line add up to 180°. Angles around a point add up to 360°. When two lines intersect, adjacent angles are supplementary (they add up to 180°) and angles across from either other are vertical (they're equal).
