AC=52

Explanation:

.
In a square, both diagonals are equal to each other. This means that if we can find the length of BD we will have found the length of AC.

Also, in a square, the diagonals bisect each other. This means that BD is twice the length of AE. We can write the equation for this and use it to solve fo rx:.

10x-48=2(3x-4)

10x-48=6x-8

4x=40

x=10

Now, we can plug this value in for the equation for BD:

BD=10(10)-48=100-48=52
