To add the polynomials \( (4x^2 - x + 5) + (5x^2 + x + 9) \), we combine like terms.
1. Combine the \( x^2 \) terms:
\[
4x^2 + 5x^2 = 9x^2
\]
2. Combine the \( x \) terms:
\[
-x + x = 0x \quad (\text{which simplifies to } 0)
\]
3. Combine the constant terms:
\[
5 + 9 = 14
\]
Now, putting it all together, we have:
\[
9x^2 + 0x + 14
\]
The polynomial in standard form is:
\[
\boxed{9x^2 + 14}
\]
