Find (f • g) when f(x) = x^2 + 5x + 6 and g(x) = 1/x+3

option D

Step-by-step explanation:

(fog)(x) = f(g(x))

Plug in g(x) in f(x)

We plug in 1/x+3 in the place of x  in f(x)

To simplify it we take LCD

LCD is (x+3)(x+3)

All the denominators are same so we combine the numerators

Option D is correct

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

1) 2/5

2) zero=0/1

3) zero=0/2

4) -4/5

5) undefined=3/0
