Answer:
XY = 16 ft
Step-by-step explanation:
The mid segment DE is half the sum of the parallel bases, that is
= 20 ( multiply both sides by 2 to clear the fraction )
XY + WZ = 40
XY + 
XY = 40 ( multiply through by 2 to clear the fraction )
2XY + 3XY = 80
5XY = 80 ( divide both sides by 5 )
XY = 16
The answer would be Addition property of equality i belive
A i think if not i’m sorry
You add 25 and 12 i think
The first step is to subtract 6 from both sides to cancel it out. You will be left with -3x= -1.
