<PRE><B>Question 211758</B>
Kim traveled 2x + 50 miles on Monday and 3x – 10 miles on Tuesday. 
Write a polynomial that represents the total distance traveled in two days. 
Find the total distance if x = 20. 
---------------------------------------
Total distance = 2x+50 + 3x-10 = 5x+40
----
So, if x = 20, total distance = 5(20)+40 = 140
