Question

In parallelogram ABCD , diagonals AC¯¯¯¯¯ and BD¯¯¯¯¯ intersect at point E, AE=x2−16 , and CE=6x . What is AC ? Enter your answer in the box. units

Answer 1

I just took the quiz and the anser i got was 96 hopes this hleps

Answer 2

In a parallelogram we know that,

Diagonals are equal and cut each other equally

So, AC= BD

and AE = CE & BE =DE

Given ,

AE= 2x-16 & CE=6x

So, 2x-16 = 6x

=> -4x = 16

=> x = -4

AC = 2× CE= 2× (6x)

= 12x

Putting the value of x,

12× (-4)

= -48

P.S.-The value cannot be negative . Please do check your question first and the data provided.
