Answer:
y = -1/4x^2 - x + 3 
Step-by-step explanation:
(-6,0) 
(-4,3)
(2,0)
36a - 6b + c = 0
16a -4b + c = 3 
4a + 2b + c = 0 
c = -4a - 2b 
36a - 6b - 4a -2b = 0
16a - 4b -4a - 2b = 3 
32a -8b = 0 
12a - 6b = 3
4a - b  = 0
4a - 2b = 1 
b = -1 
4a + 1 = 0 
4a = -1 
a = -1/4 
c = 1 + 2 = 3 
y = -1/4x^2 - x + 3 
 
        
                    
             
        
        
        
4×77. 75=311
4×31. 75=127
4×19. 25=77
4×82=328
        
             
        
        
        
Answer:
a 20 X 40 X x
b just a guess but 2 centimeters
c 1600 or 800 depending on what x is
