Answer:
sorry to answer late but..
Step-by-step explanation:
 =
 = 
the wings of the real plane are 12 meters or 1200 cm
we want to solve for the scale, sooo do the algebra...get scale by it self.. 
real *  = scale
 = scale
1200 *  = 16
 = 16
The scale model wings are 16 cm   2.54 cm is one inch so the wings are approx.  6.3 inches 
 
        
             
        
        
        
(x-5)(x+3)=0
x^2+3x-5x-15=0
(x^2+3x) (-5x-15)
x(x+3) -5(x+3)
x-5=0 x+3=0
x=5 OR -3
