Part 2: Unit 2 Review

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

Find the indicated length.

If RT=36, find the value of x.

• 3

• 4

• 5

• 6

If HJ=7x-27, find the value of x.

• 4

• 5

• 6

• 7
