Well, 60 (minutes in an hour) divided by 12 (from the problem) is 5, so you have to multiply that 5 by the 5 from the problem to find that the train is going 25 (5*5) mph. Just double this for two hours, and you result in 50!

F(x)=3^2-2and g(x) =4x+2 what is the value of (f+g)(2)

morpeh [17]

Step-by-step explanation:

$f(x) = {3}^{2} - 2 = 9 - 2 = 7 \\ g(x) = 4x + 2 \\ \therefore \: (f + g)(x) = 7 + 4x + 2 \\ \therefore \: (f + g)(x) = 4x + 9 \\ \therefore \: (f + g)(2) = 4 \times 2 + 9 \\ \therefore \: (f + g)(2) = 8 + 9 \\ \red{\boxed{ \bold{ \therefore \: (f + g)(2) = 17}}}$
