Tell which property is represented. 6. 0 + 45 = 45

7. (r+s) +t= r+(s+t)

8. 84•3 = 3•84

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
