Answer:
Explanation:
fg(x) = (x+2)(3x^2 - 1)
= 3x^3 - x + 6x^2 - 2
= 3x^3 + 6x^2 - x - 2
gf(x) = (3x^2 - 1)(x + 2)
= 3x^3 + 6x^2 - x - 2
As you can see:
fg(x) = gf(x)
3x^3 + 6x^2 - x - 2 = 3x^3 + 6x^2 - x - 2

Answer:
110
Step-by-step explanation:
Let x = rate #1 and then 155-x=rate #2.
15x + 5(155-x) = 1225
15x - 5x + 775 - 1225
10x = 450
x = 45, second rate is 110
