Answer:
Step-by-step explanation:
A function is quadratic if you can express it in the form :
f(x) = Ax² + Bx + C
and that A is non-zero.
The highest degree variable is 2 (i.e x² is the highest exponent)
 
                                
             
                    
              
              
                
                
Answer:

1.) for the odds would be 2/3 against would be 1/3
2.) i think it would be 157.08 (157 if rounded)
3.) he could make 18 arrangements 
        
             
        
        
        
(7x-6)(8x+3)
Use the FOIL method
F:  7x • 8x = 56x^2
O: 7x • 3 = 21x
I: -6 • 8x = -48x
L: -6 • 3 = -18

Simplify
