1. The problem is to simplify the expression $$\frac{6}{c+5} + \frac{7}{c+2}$$.
2. To add these fractions, we need a common denominator. The common denominator is $$(c+5)(c+2)$$.
3. Rewrite each fraction with the common denominator:
$$\frac{6}{c+5} = \frac{6(c+2)}{(c+5)(c+2)}$$
$$\frac{7}{c+2} = \frac{7(c+5)}{(c+5)(c+2)}$$
4. Now add the numerators:
$$\frac{6(c+2)}{(c+5)(c+2)} + \frac{7(c+5)}{(c+5)(c+2)} = \frac{6(c+2) + 7(c+5)}{(c+5)(c+2)}$$
5. Expand the numerators:
$$6(c+2) = 6c + 12$$
$$7(c+5) = 7c + 35$$
6. Add the expanded numerators:
$$6c + 12 + 7c + 35 = (6c + 7c) + (12 + 35) = 13c + 47$$
7. So the expression becomes:
$$\frac{13c + 47}{(c+5)(c+2)}$$
8. This is the simplified form since the numerator cannot be factored further to cancel with the denominator.
Final answer:
$$\frac{13c + 47}{(c+5)(c+2)}$$
