To evaluate $\frac{m}{n}(x)$ for $x=-3$, we first need to find the expressions for $m(x)$ and $n(x)$.<br /><br />Given:<br />$m(x) = x^2 + 4x$<br />$n(x) = x$<br /><br />Now, let's find $\frac{m}{n}(x)$:<br />$\frac{m}{n}(x) = \frac{x^2 + 4x}{x}$<br /><br />Simplifying the expression:<br />$\frac{m}{n}(x) = x + 4$<br /><br />Now, we can evaluate $\frac{m}{n}(x)$ for $x=-3$:<br />$\frac{m}{n}(-3) = -3 + 4 = 1$<br /><br />Therefore, $\frac{m}{n}(-3) = 1$.
