It would be A because they’re both perfect squares
X=23
I say this because you can see that the scale factor is 3 due to just visually scaling both the long and short leg from the original triangle to the dilated triangle. Dividing 39 by 3 is 13, and doing it in reverse. Adding 10 would equal 23, the initial value. So that'd be the missing value.
Let x=bob’s original amount of money
Let 9x=Bessy’s original amount of money
9x+4=5(x+4)
9x+4=5x+20
4x=16
x=4
9(4)=36
Bob had $4 before earning $4 and Bessy had $36 before earning $4
