You need to find the change in x and y 
change in x = 12 
change in y = 16 
to find the distance you use a^2+ b^2 = c^2
or in this case x^2 + y^2 = d^2
144+256 = 400 

=20 
so distance equals 20
I hope this helps!
 
        
        
        
Answer: 0.85 or %85
Fraction = 68 over 80 divide by two twice 17 over
                                                            20
Percent = 68/80 = 0.85 x 100 = 85%
Decimal =  0.85
 
        
                    
             
        
        
        
Answer: See below
Step-by-step explanation:
27.  -(a-3)
28.  (b-1)(b+3)
29.  (c+4)(c+5)
30.  d(d+5)
31.  -(3/4)(2e-5)
Sorry - I don't have time to enter the details.  Look for areas where the expressions can be factored in a manner that forms as many equivalent expressions in both the numerator and denominator.
For example:  In problem 30:
(5d-20)/(d^2+d-20) * [??]/20d = 1/4
Factor:  
   <u>(5(d-4))</u>       <u>d(d+5)</u>        = 1/4
(d-4)(d+5<u>)</u>       20d
The (d-4), d+5, and d terms cancel, leaving
5/20 = 1/4
