Answer:
see below
Step-by-step explanation:
5t+9t and 14t
Becuase the two numbers have the same variable, you can add them together. The exponents do not change.
5+9=14
5t+9t= 14t
5t +9t is equivalent to 14t
5t -9v is not equivalent to 9v-5t
5(9t-5) is not equivalent to 45t-5 because 5(9t-5) is 45t-25
t +t + t +v is not equivalent to 4tv
