Question

Help me with this parallelogram please :)

Answer 1

• 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 2

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
