To answer this question, you must remember the equation:
a²+b²= c²
(6.4)² + (12)²=   (12.2)²
<span>40.96 + 144 = 184.96
</span> (12.2)² = <span>148.84
</span>
184.96 ≠ 148.84
This cannot be a triangle
hope this helps
        
             
        
        
        
Answer:
 
dissociation of acetic acid (like vinegar) in water 
Explanation:
CH3COOH is basically vinegar (aka acetic acid)
dissociation of acetic acid in water 
so when you put vinegar in water it makes 2 hydrogen ions (H+) and acetate ( CH3C00 ) a chemical that used in making film
 
        
             
        
        
        
Reproducible is the term where your answers are similar to other groups. If every other group has similar results as yours (only if you use the same measurements) your results are reproducible. If your results are different to every other group your results aren't reproducible.  <span />
        
                    
             
        
        
        
Answer:
-2 
Explanation:
Since its a compound, it's charge is 0. 
So, there are 2 Fe and 3 Oxygen, 
let x = oxidation number of oxygen
2(+3) + 3x =0 
 x =-2 
Side note : even if the oxidation number is positive, make sure to put the positive sign like how you would in numbers
