Answer:
40
Step-by-step explanation:
5 people in the room have 5*40 = 200 years altogether
a new person is X years old.
Now 6 people have (200 + x) years altogether.
Mean age of 6 people is (200+x)/6. and it is also = 40.
So,
(200+x)/6 = 40
200 + x = 240
x = 40
F(x)= 3 (x^2 + 4x +4) - 6
= 3x^2 + 12x +12 -6
= 3x^2 + 12x + 6
