Answer 1

Answer:

parallelogram's diagonal bisect each other

means 4y-7 = y+11

and 3x-14 = X+2

first diagonal second diagonal

4y-7=y+11. 3x-14 = X+2

4y-y =11+7. 3x-x = 2+14

3y = 18 2x = 16

y= 18/3 x = 16/2

y= 6. x =-8

first diagonal. second diagonal

4y-7+y+11. 3x-14+X+2

4(6)-7+(6)+11. 3(8)-14+(8)+2

24-7+6+11. 24 -14 +8+2

34. 20

(c) is right
