what about your last question @kayla2001 you never finished

mathstudent55 · Answer

Let x be the number of times Rex goes to the pool.
Then 3x is the fee for all the visits.
The fixed membership is 20, so you add 20 to 3x.
What do you get?

No. 
3x and 20 are not like terms. They can't be combined.
3x added to 20 is simply 3x + 20
