A. (f + g)(x) = f(x) + g(x) = 4x - 5 + 3x + 9 = 7x + 4
B. f.g (x) = f(x) * g(x) = (4x - 5)*(3x + 9) = 12x^2 + 36x - 15x - 45
= 12x^2 + 21x - 45
C Replace the x in f(x) by g(x):-
= 4(3x + 9) - 5
= 12x + 36 - 5
= 12x + 31

I think the 3rd one idk wait for someone else to answer go compare
Answer: -2511 (if the periods mean multiplication)
Step-by-step explanation:
I’m not sure whether you’re trying to have the periods be multiplication, but if that’s what they are, this is the answer
5x10-2x8x16x10-1
50-16x160-1
50-2560-1
-2511
Again, I’m not sure if that’s what you mean but I can’t really see what else they would mean since you can’t have a 3 part decimal
