Answer:
x =0
Step-by-step explanation:
Solve for x over the real numbers:
sqrt(x) = 0
Square both sides:
Answer: x = 0
 
        
                    
             
        
        
        
                                                                   s = 2(lw + lh + wh)
Divide each side by  2 :                            s/2 = lw + lh + wh
Subtract 'lh' from each side:                s/2 - lh = lw + wh
Combine the 'w' terms:                        s/2 - lh = w(l + h)
Divide each side by (l + h):  (s/2 - lh) / (l + h) = w
