I’m not sure what the choices are so I don’t know what the correct answer is but expressions that could be equivalent are

r+r+t+r

3r+t
PoeticAesthetics

2r + (t + r) is the same thing as 2r + t + r

To solve this combine like terms. In this case the like terms are 2r and r

2r + t + r

2r + r OR 2r + 1r

3r

3r + t

2r + (t + r) = 3r + t

Hope this helped!
