Option 1: 7x/5x+7

Option 2:

Option 3:

Answer 1

To determine which rational expressions can be simplified, we need to look for any common factors in the numerator and denominator.

1. Option 1: $\frac{7x}{5x+7}$

   In this expression, the numerator is $7x$ and the denominator is $5x+7$. There are no common factors in the numerator and the denominator (since $5x+7$ cannot be factored and $7x$ does not share any factors with it). Thus, this expression cannot be simplified.

2. Option 2: (please provide the expression)

3. Option 3: (please provide the expression)

Please provide the expressions for Options 2 and 3 so I can assist you further in determining if they can be simplified.
