\( \frac{x+4}{x+8} \quad \) y \( \frac{3 x+6}{x+8} \)

It looks like you're presenting two rational expressions: 1. \( \frac{x+4}{x+8} \) 2. \( \frac{3x+6}{x+8} \) If you want to perform an operation with these two expressions, such as addition, subtraction, multiplication, or division, please specify which operation you would like to perform. For example, if you want to add them, you would do: \[ \frac{x+4}{x+8} + \frac{3x+6}{x+8} = \frac{(x+4) + (3x+6)}{x+8} = \frac{4x + 10}{x+8} \] If you want to multiply them, you would do: \[ \frac{x+4}{x+8} \cdot \frac{3x+6}{x+8} = \frac{(x+4)(3x+6)}{(x+8)(x+8)} \] Please clarify what you would like to do with these expressions!
