Answer:
This cannot factor
Step-by-step explanation:
This cannot factor because there is no number that can be factored out of all of the terms.
 
        
             
        
        
        
 For this case we must find the product of two mixed numbers:

So, we have:

If we go to a mixed number we have:

Answer: AC=12 cm
Step-by-step explanation:
 To  solve this problem you must apply the law of sines, as you can see below:
 
 Where:
 a=13
 A=85.2°
 B=71.6°
 Therefore, you must solve for b, then, you obtain that the lenght AC asked in the problem above is:
 
 
 
        
                    
             
        
        
        
So you have your polynomial. To factor this out, you need to find the factors of -45 that will add up to 3. These two factors would be -5 and 8. So, you have factored your polynomial! (x-5)(x+8). If you are still unsure, simply use the FOIL method to check and see if you get the same polynomial back. Hope this helps!
