oksian1 [2.3K]

Answer:

31 units

Step-by-step explanation:

When the figure is a parallelogram, opposite sides have the same measure:

AD = BC

3x +7 = 5x -9 . . . . . . substitute given expressions

16 = 2x . . . . . . . . . . . add 9-3x

8 = x . . . . . . . . . . . . . divide by 2

Use this value of x in the expression for AD to find its required length:

AD = 3(8) +7 = 24 +7

AD = 31 . . . . units

The length of segment AD must be 31 units for ABCD to be a parallelogram.
