ABCD is a rectangle, if AC is 2(x-3) and BD is X+5 what are the lengths of the diagnoals?

a. 2,2
b. 11,11
c. -3,-3
d. 16,16

  • math -

    In any rectangle the diagonals are equal, so .....

    2(x-3) = x+5
    2x - 6 = x+5
    x = 11
    subbing into either one gets us 16
    so the choice is d)
