To solve for \( F(5) + G(6) \), we first need to calculate \( F(5) \) and \( G(6) \) separately using the given functions.

Starting with \( F(x) = x^2 + 5x \), we substitute \( x = 5 \):

\[

F(5) = 5^2 + 5(5)

\]

\[

= 25 + 25

\]

\[

= 50

\]

Next, we calculate \( G(x) = 2x + 1 \) with \( x = 6 \):

\[

G(6) = 2(6) + 1

\]

\[

= 12 + 1

\]

\[

= 13

\]

Now, we add the results from \( F(5) \) and \( G(6) \):

\[

F(5) + G(6) = 50 + 13

\]

\[

= 63

\]

Thus, the correct answer is 63. The calculations reflect the application of the quadratic and linear function rules, leading to a straightforward evaluation of the expressions based on critical substitution
