  • Parallel sides of parallelogram are equal in length


\\ \sf\longmapsto AD=BC


\\ \sf\longmapsto 6x+14=9x-4


\\ \sf\longmapsto 9x-6x=14+4


\\ \sf\longmapsto 3x=18


\\ \sf\longmapsto x=6

  • AD=6x+14=6(6)+14=36+14=50

Option D

Answer:

D. 50

Explanation:

solve for x first

9x-4=6x+14 (+4)

9x=6x+18 (-6x)

3x=18

x=6

plug in variable now

6*6=36+14=50
