5. In $\triangle A B C$, one side is 5, and the other two sides are exactly the two roots of the equation $2 x^{2}-12 x+m=0$. Then the range of values for $m$ is
5. Let the two roots of $2 x^{2}-12 x+m=0$ be $x_{1}, x_{2}$. Clearly, $x_{1}>0, x_{2}>0$. Therefore, $x_{1} x_{2}=\frac{m}{2}>0, x_{1}+x_{2}=6>5$, and $\left|x_{1}-x_{2}\right|0$, so from $\left|x_{1}-x_{2}\right|^{2}\frac{11}{2}$. That is, $\frac{11}{2}<m \leqslant 18$.
