Answer:
I have no idea, but I think there are two fourteenths in 2/7.
 
        
             
        
        
        
(a-4)(a-5) goes with b
(a-10)(a-2) goes with d
(a-4)(a+5) goes with a
(a-10)(a+2) goes with c
e is not used. 
if you want to check take the pairs and foil or box them out. 
        
                    
             
        
        
        
429 ÷ 39= 11
11 ÷ 2= 5.5 (5 1/2)
It takes 5 1/2 weeks to produce 429 wetsuits
        
             
        
        
        
Answer:
2 imaginary roots
Step-by-step explanation:
The discriminate is the portion of the quadratic equation under the square root
D = b^2 - 4ac
D = 8^2 - 4(2)(16)
D = 64 - 128
D = -64
Since the discriminate is negative the square root will be imaginary
and there will be 2 of them
2 imaginary roots
