DEFG is a parallelogram. Segment DH = 2x + 6, segment HF = 4x + 1, segment HE = 3x + 2 and segment GH = 20. Find the value of x. http://curriculum.kcdistancelearning.com/courses/GEOMx-HS-A09/a/assessments/Semester1Exam/Geometry_SemesterA_Final_235q.gif
base on your info, something doesn't make sense because DH = HF and HE = GH, you have 2 different value of x
you are right I made mistake DH= 2y+6 not 2x+6
then use HE = GH, can you get x from here ?
