See explaination 
Step-by-step explanation:
B. The equality relation on the real numbers is an equivalence relation. 
This statement is true 
C. If RR is a reflexive relation on a set S, then any two RR- related elements of S must also be R2R2 related. 
This statement is true 
F. The less than or equal relation on the real numbers fails to be an equivalence relation because it is reflexive and transitive but not symmetric
This statement is true 
H. If RR is an equivalence relation, then R2

Answer:
the answer is 15
Step-by-step explanation:
density= total population/surface area
density= 375/5^2
density=375/25=15
 
        
             
        
        
        
1cm = 16km
1cm • x = 23.1cm
x = 23.1
16km • 23.1 = 369.6km
The real distance is 369.6km.
