Step-by-step explanation:
If y is largest number, you want y, and the two next smaller even integers smaller than y - i.e. y, y-2, and y-4
The sum of these is y + (y-2) + (y-4).
This simplifies to 3y - 6 or 3(y - 2)
Since we don’t know what y is, this is as far as we can solve the problem.
 
        
             
        
        
        
The answer is 6*square rooted*2
        
             
        
        
        
Answer:
Each time, the x is being multiplied by -3 to result in the output.
So for every x input, multiply by -3.
For the y output for 15, you would divide by -3 to find the input x
For example, when 7 is the input, multiply by -3, and the output y would result in -21.
 
        
                    
             
        
        
        
The sum of angles in triangle is equal to 180 degrees, so
<R =180-56-30
<R=94
 
        
                    
             
        
        
        
Insert x = 7 
so 3/(7+2) - sqr (7-3)
=3 / (9) - sqr (4)
= 1/3 - 2 
=1/3 - 6/3 
= -5/3
