Answer: The correct option is D.
Explanation:
It is given that the triangle ABC is an isosceles triangle. It is also given that the line BD is the median of triangle ABC.
Since DB is median it means point D divides the line AC in two equal parts.
The The median of an isosceles triangle is always a perpendicular bisector of the opposite side. Since the median is perpendicular on side AC, therefore the sides AB and CB are equal.
In triangle ABD and CBD,
.... (Isosceles triangle)
.... (D is midpoint of AC)
.... (Common Side)
Therefore option D is correct.

Answer:
mother=m
e=emily
m=4e
m+6=3(e+6)
substitute the first equation into the second.
4e+6=3(e+6)
4e+6=3e+18
4e=3e+12
e=12
