RM=

• RM=6

• RM=3

• RM=12

• RM=9

B is the midpoint of AC.  Find AB.

• 2

• 16

• 8

• 4

If DF=9x-39, find EF.

• 16

• 58

• 116

• 23

Write an equation that correctly models the lengths shown.

• 3x + 2 + 6 = 2x - 2

• 2x - 2 + 6 = 3x + 2

• 6 - 3x - 2 = 2x - 2

• 2x + 2 + 3x + 2 = 6

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

• 2x + 22 = 12

• 12 + x + 11 = x + 11

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

• 8 + x + 3 = -17 + 2x

• x + 3 + -17 + 2x = 8

• 8 + -17 + 2x = x + 3

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

• 9 - x = 2x - 19

• 9 + x = 2x -19

• x + 2x - 19 = 9

• 9 + 2x - 19 = x

Find the length indicated.
