Just multiply 42 by 10 and that gives you 420 , so the real car has a length of 420cm or 4.2 metres :)
        
                    
             
        
        
        
Mallory purchased 8 oranges. 
6*0,75+n*1,25=14,50
        
                    
             
        
        
        
A.6x=5(x+10)
b.6x=5x+50
    x=50
c. 6(50)=5((50)+10)
   300 = 5(60)
   300= 300
        
             
        
        
        
Answer:
A. Trinomial
Step-by-step explanation:
It says it's a polynomial and that based on the number of terms. So right then you can cancel out cubic and quadratic because they aren't polynomials. Also:
Cubic is just a variable with the exponent of 3. Examples:

Binomial is a polynomial with 2 terms. Examples:

A quadratic has a division sign.
