Calculate the value of Kc

Given:

\[ \text{Mg(OH)}_2 (s) \leftrightarrow \text{Mg}^{2+} (aq) + 2 \text{OH}^- (aq) \quad K_c = 5.60 \times 10^{-12} \]

\[ \text{F}^- (aq) + \text{H}_2\text{O} (l) \leftrightarrow \text{HF} (aq) + \text{OH}^- (aq) \quad K_c = 1.47 \times 10^{-11} \]

Calculate \( K_c \) for the following (Change equations above so they sum to the equation below).

\[ \text{Mg(OH)}_2 (s) + 2 \text{HF} (aq) \leftrightarrow \text{Mg}^{2+} (aq) + 2 \text{F}^- (aq) + 2 \text{H}_2\text{O} (l) \quad K_c = ? \]
