It is necessary when you are getting into multiplying from the outside of parenthesis and multiplying variables inside of parenthesis. 
ex: 5(3 + 3x)
5 * 3 = 15
5 * 3x = 15x
so final set up would be 15 + 15x  
        
                    
             
        
        
        
Answer: Ann's distance from home staying is increasing the fastest from the 5th to the 6th minute
Step-by-step explanation: The slope from the 5th minute to the 6th minute is 40, meaning that she increased 40 mph in one minute. This increase is greater than any other time periods. At first, you might think that minute 0 to 1 is the greatest but the slope from minute 0 to 1 is actually 30 mph, so therefore my answer can be proven correct.
