As the general growth formula is
where A = Amount after growth
P = Original amount
r = yearly growth rate

Answer:
Solution given:
now
f(x)+g(x)=....(1)
now
factoring x²+6x-40
we get
x²+10x-4x-40
x(x+10)-4(x+10)
(x+10)(x-4)
now substituting in equation 1 ,we get
f(x)+g(x)=
taking l.c.m
=
=now
opening bracket
=
So
answer is :
B.
