Step-by-step explanation:
these two triangles are similar
therefore corresping sides are proportionate
12/8=9/x
12x=72
x=72/12=6
So first you would divide 1950/6 to find the amount for one year of their age.

Answer:
1820
Step-by-step explanation:
The sum of the first n terms of a geometric series with common ratio r and first term a is:
a(1-r^n)/(1-r). Plugging this in 5(1-3^6)/(1-3)=1820
Difference of two squares will be
16y^2 -x^2 = (4y -x)(4y +x)
so the second choice
