To simplify the expression \( 19 + 6x + 5^2 \), we first calculate \( 5^2 \):
\[ 5^2 = 25 \]
Now we substitute this back into the expression:
\[ 19 + 6x + 25 \]
Next, we combine the constant terms \( 19 \) and \( 25 \):
\[ 19 + 25 = 44 \]
Now the expression simplifies to:
\[ 6x + 44 \]
Thus, we can write it as:
\[ 6x + 44 \]
However, note that none of the options provided match this expression. Therefore, the answer is:
None of the options are correct, as the simplified expression is \( 6x + 44 \).
