The Segment Addition Postulate

Find the indicated length.

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.

• 9 - x = 2x - 19

• 9 + x = 2x -19

• x + 2x - 19 = 9

• 9 + 2x - 19 = x
