5x^2-4x+1 + -3x^2+x-3= 2x^2-3x-2 
 
        
             
        
        
        
Answer:
Step-by-step explanation:
y=-1
because when y = - 1, 
it is an equation of x axis.. hence it will parallel to x axis....
 
        
                    
             
        
        
        
L=16
W=21
Set up a systems of equations: 
x=length 
y=width 
xy=336
x+5=y
Use substitution to solve: 
x(x+5)=336
x^2+5x=336 
Solve using factoring: 
x^2+5x-336=0
(x-16)(x+21)=0
x=16 and x= -21 
Since length can't be negative, l=16 
To find width, plug length into the first equation: 
(16)y=336
y=21 
So...
L=16

Answer:
62%
Step-by-step explanation:
31/50 is also equal to 62/100 (if we multiply the numerator and denominator by 2). 62/100 is 62%.
