Quadrilateral QUAD is a parallelogram. DC=4x-7 and CU=2x+3. Calculate the length of DU.

The diagonals of a quadrilateral  bisect  each other......therefore....

 

DC =  CU

 

4x - 7   =  2x + 3

 

4x - 2x  =  3 + 7

 

2x  = 10

 

x =  10  / 2    =  5

 

Therefore  

 

DU =  2 DC =  2  ( 4(5) - 7 )  =   2  ( 13)  =   26
