Answer

$\dfrac{1}{3}$

Work Step by Step

To find the limit, we apply the rule: $\lim\limits_{x \to a} \dfrac{A(x)}{B(x)}=\dfrac{\lim\limits_{x \to a} A(x)}{\lim\limits_{x \to a} B(x)}$ Since, $x \to 2$, then we can write: $|x-2|=x-2$ $\lim\limits_{x \to 2^{+}} \dfrac{|x-2|}{3x-6} =\lim\limits_{x \to 2^{+}}\dfrac{x-2}{3x-6} \\=\lim\limits_{x \to 2^{+}}\dfrac{x-2}{3(x-2)}\\=\dfrac{1}{3}$
