Best ResponseYou've already chosen the best response.1Assuming the rhombus is ABCD and E is the intersection of the diagonals, then we know the diagonals perpendicularly bisect each other, so AE is half of one diagonal and BE is half the other diagonal. That allows us to solve for x: (x+4) + (2x3) = 20/2 3x + 1 = 10 3x = 9 x = 3 and since BE = 2x  3 = 3 is half of BD, BD = 2*3 = 6 (answer C).

Best ResponseYou've already chosen the best response.1For some reason i thought it was the other one. But it will be 14 in that case.
