Question 1

For each prism, shade one of its bases.

Question 2

The volume of both of these trapezoidal prisms is 24 cubic units. Their heights are 6 and 8 units, as labeled.
What is the area of a trapezoidal base of each prism?

Question 3

Two angles are complementary. One has a measure of 19 degrees.

What is the measure of the other?

Question 4

Two angles are supplementary. One has a measure that is twice as large as the other.

Find the two angle measures.

50 degrees

100 degrees

20 degrees

140 degrees

60 degrees

120 degrees

40 degrees

Question 5

Match each expression in the first list with an equivalent expression from the second list.

Draggable item		Corresponding Item
7(x+2)-x+3		6x+17
\frac{-2}{5}x-7+\frac{3}{5}x-3		2(5x+4)
6x+3+4x+5		\frac{1}{5}x-10
24x+36		8x+(-5)+4+(-9)
8x-5+4-9		12(2x+3)

Question 6
