temp is 233 and 468K and other information are visible

Two objects, A and B. initially at 233 K and 468 K, respectively, are brought into contact with each other. Over this range of temperatures the heat capacity of object A and object B can be approximated by the following equations CA - 4 + 0.08 T andCa - 6+ 0.07 7 Through the exchange of heat the two objects eventually obtain a common final temperature. What is this final temperature (in k)
