F(g(2))
g(2)=2^2+1=4+1=5
f(5)=5-3=2
f(g(2))=2
Answer:
Option D. c = 45 will be the answer.
Step-by-step explanation:
In the figure attached there are two similar parallelograms PARL and WXYZ.
In which AP = 15, PL = 40, WZ = 120 and WX = c
By the property of similarity, corresponding sides of the given parallelograms will be in the same ratio.


c =
[By cross multiplication]
c = 45
Therefore, Option D. c = 45 will be the answer.

Therefore, a is 7 aka real part and b is 19 which is imaginary part.
There started with 50 and it doubles so that means:
100 at the end of year 1
200 at the end of year 2
400 at the end of year 3
800 at the end of year 4
Only the first choice is correct.
sorry about my previous comments; they were from misunderstanding.
