16 girls. 12 divided by 4 is 3, so this means that you have to take 4 and multiply it by 4 which equals to 16.
Answer:
I think you need to put more info
Step-by-step explanation:
Let's use a simple way. SPOE, APOE, DPOE, MPOE.
First, isolate the variable.
x5 + 3 = 2
-3 -3
x5 = -1/5 (5 divided by -1)
Answer to 5 divided by -1: -5.
A is the answer. (I'm pretty sure.)

~Realistic
All the triangles are similar, so the ratio of (long leg)/(short leg) is the same. The long leg of ΔADB is
.. AD = AC -DC = 20 -4
.. AD = 16
Then
.. (long leg)/(short leg) = AD/DB = BD/DC
.. 16/h = h/4
.. h^2 = 64
.. h = 8
Selection D is appropriate.
_____
You may see this again. The altitude (h) from the right angle in a right triangle is the geometric mean of segments AD and DC. That is,
.. h = √((AD)*(DC))
