Answer:
B and D
Step-by-step explanation:
a. 5t+4t =9t
b. t+5+4= t+9
c. 9t
d. 4×5×t= 20t
e. t(5+4)- do the inside the parenthesis first. =9t
the answer would me B and A because the answer isn't 9t so it would be those!! also the boxes on the right you multiply t×5 and t×4 and that would be 5t + 4t =9t
