Final answer:

To find f(2)+g(7), you first calculate f(2) as 8 and g(7) as 49, then add the two to get the result, which is 57.

Step-by-step explanation:

To find f(2)+g(7), we need to evaluate the functions f(x) and g(x) at x=2 and x=7, respectively. The given functions are f(x)=5x-2 and g(x)=x2.

First, let's find f(2):


f(2) = 5(2) - 2 = 10 - 2 = 8.

Next, let's find g(7):


g(7) = (7)2 = 49.

Now, we add the two results together:


f(2) + g(7) = 8 + 49 = 57.

Therefore, f(2) + g(7) is equal to 57.
