Answer:

#3q +2z#

Explanation:

An expression is a maths sentence or maths statement.
There are two numbers mentioned, # q and #z

'Tripled' means multiplied by #3#, so #q# tripled is #3q#

'Doubled' means multiplied by #2#, so #z# doubled is #2z#

The required expression is a statement that these two terms are added together:

#3q +2z#

Notice that we are not told what the answer must be equal to, so we cannot write an equation.
