Answer 1

`(3(6)-1)/(2(6)+1)`

Explanation:

We know that r(x) = 3x - 1 and s(x) = 2x + 1, and we are to find which of the given expressions in the possible answer options is equivalent to
`((r)/(s) )(6)`.

r(x) = 3x - 1

s(x) = 2x + 1

The ratio for r/s(x) will be equal to 3x - 1/2x + 1 and x is 6 here so substituting this value to get:

`(3(6)-1)/(2(6)+1)`

Therefore, option A is the correct answer.
