Answer:

12. x = 11; sides are 29

13. x = 5; sides are 25

Step-by-step explanation:

12. The marked sides are equal length, so ...

3x -4 = 2x +7

x = 11 . . . . . . . . add 4-2x

2x+7 = 2(11)+7 = 29 . . . side lengths

__

13. The marked sides are equal length, so ...

6x -5 = 5x

x = 5 . . . . . . . add 5-5x

5x = 5(5) = 25 . . . side lengths
