The basketball team practiced for h hours. the baseball team practiced for 3 more hours than the basketball team. write an expression that represents the number of hours that the baseball team practiced.

An expression that represents this amount of practicing is formed by first writing the original expression you will be building upon.
This leaves you with:
h

This represents the number of hours that the basketball team practiced. To find the number of hours that the baseball team practiced, you’d multiply that expression by 3.
This results in:
3h -or- 3(h)

So the expression that represents the hours that the baseball team practiced is 3h.

I hope this helps! :)
