If T is the midpoint of SU, find x.

• 3

• 4

• 5

Suppose AC =  48, find the value of x. Then, find the length of AB.

• 13

• 16

• 12

• 15

Find the length indicated.

Write an equation that correctly models the lengths shown.

• 2x + 20 + x + 21 = 9

• 2x + 20 + 9 = x + 21

• 9 + x + 21 = 2x + 20

• 2x + 20 - 9 = x + 21

Write an equation that could be used to relate the lengths shown.

• 4 + 3x + 2 = 7x - 2

• 7x - 2 + 4 = 3x + 2

• 7x - 2 + 3x + 2 = 4
