To simplify the expression \(\frac{35\sqrt{x^2 + 10x + 25}}{x + 5}\) given that \(x > -5\), we start by simplifying the expression under the square root.
First, observe that:
\[ x^2 + 10x + 25 = (x + 5)^2 \]
Thus, we can rewrite the expression:
\[ \sqrt{x^2 + 10x + 25} = \sqrt{(x + 5)^2} \]
Since \(x > -5\), \(\sqrt{(x + 5)^2} = x + 5\).
Now replace \(\sqrt{x^2 + 10x + 25}\) in the original expression:
\[ \frac{35\sqrt{x^2 + 10x + 25}}{x + 5} = \frac{35(x + 5)}{x + 5} \]
Since \(x + 5\) is on both the numerator and the denominator (and not equal to zero when \(x > -5\)), we can simplify this to:
\[ 35 \]
So, the simplified expression is:
\[ \boxed{35} \] for \(x > -5\).
