The Quadratic Formula uses the "a", "b", and "c" from "ax2 + bx + c", where "a", "b", and "c" are just numbers; they are the "numerical coefficients" of the quadratic equation. Therefore, 
f(x) = x2 – 5x + 6
a = 1
b = -5
c = 6
        
             
        
        
        
Answer:
Answer below       Please give brainliest!!  
Step-by-step explanation:
Sue Black:  8x5=40 hours    40 x $6.75 = $270
Jerry Atrix:  7.25 + 3 + 6.75 + 8 + 5 = 30 hours
                     30 x $5.15 = $154.50
Sam Ting:  7.75 x 5 = 38.75 hours
                  38.75 x $8.75 = 339.0625 = $339.06

Answer:
<h2>128m³</h2>
Step-by-step explanation:
Volume = L x W x H
L = 4
W = 4
H = 8
Volume = 4 x 4 x 8
Volume = 16 x 8 = 128m³
 
        
                    
             
        
        
        
2 = $1.45
1 = $0.725
