Obviously, it's not rational, because it's the sum of two square roots, so cancel out A and B right away.
If we solve it
 
sqrt (18) + sqrt (2)
= sqrt (9*2) + sqrt (2)
= 3 sqrt (2) + sqrt (2)
= 4 sqrt (2)

Answer:
The answer is 8.34
U have to use the SOH CAH TOA method
In this case I used tan
so,
tan 50= BC/7
solve for BC= 7* tan 50= 8.34
 
        
             
        
        
        
In the expression 4(x), 4 represents the number of legs, and x represents the height of the coffee table. 
 Altogether this expression shows the total length of all legs from the coffee table and kitchen table combined.
