What is the simplified form of the quantity of x plus 5 all over the quantity of 9 the quantity of x plus 4 all over the quantity of x plus 6?

To simplify the expression (\frac{x + 5}{9} \div \frac{4}{x + 6}), we can multiply by the reciprocal of the second fraction: (\frac{x + 5}{9} \cdot \frac{x + 6}{4}). This gives us (\frac{(x + 5)(x + 6)}{36}). Thus, the simplified form of the expression is (\frac{(x + 5)(x + 6)}{36}).
