 represents the number of nickels, write an algebraic expression in terms of  x  that represents the value of all the coins in  the meter in cents.  Simplify the expression. Example 7.   The length of a rectangle is  8  less than  5  times its width.  The width is increased by  3 while the length is unchanged.  Using  x  as the variable, express the change in area in terms of  . x Example 8.   If a square of side  x  is cut out of a rectangle whose dimensions are  8  by  , 10  express the remaining area in terms of  . x Example 9.   If a square has a side of  x  cm and the side is decreased by  6  cm, express the change in area in terms of  . x Example 10.   The length of a rectangle is  4  more than twice its width.  The length is increased by  7  and the width is increased by  . 2   Using  x as the variable, express the change in area in terms of  . x Examples 11 – 14.   Express the area of each shaded region in terms of  . x r % 5 . 2 % 3 % 4 % 5 . 4 % 5 2 ) 1 ( 500 r +

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
