Answer:
The length of BC would be 12.2 mm.
Step-by-step explanation:
Given,
In triangle ABC,
∠BAC = 90°,
Thus by the Pythagoras theorem,
We have,
AB = 9.6 mm and CA = 7.6 mm,
By substituting the values,
Step-by-step explanation:
 
        
             
        
        
        
Answer:
The answer is A.
Step-by-step explanation:
Lets call f(x)=y, so y= 4*(3*x-5), we want to find 'x', using 'y' as a the variable.

Now lets change the name of 'y' to 'x', and 'x' to f^-1(x).
 f-1(x) = (x+20)/12
