Answer:
12
Step-by-step explanation:
Perimeter of ΔABC = 12+ perimeter of ΔACD
Perimeter of ΔABC= AC+CB+BA
Perimeter of ΔACD=AC+CD+DA
But, CB=CD +DB
DA ≅DB since there is a ⊥bisector trough D and
Therefore,
Perimeter of ΔABC= (AC+CD+DA)+BA = Perimeter of ΔACD +12 therefore AB=12

Answer:
9 zebra fish and 5 neon tetras. White
For a cylindrical tank, volume = πr²h
Where r = radius = diameter/2 = 6/2 = 3m
height , h = 3m
Volume = 3.14 * 3² * 3 = 84.78
Volume ≈ 84.8 m³
Option D.
Between 29 and 31......maximum is 31
