Now let’s look at Ch 5.6 #14.

Parts a-c are similar – so will do part c since the harder.

Area = x + 20 = (x-1)4 > I am just stating all things that are equal based on the given.

x+20 = (x-1)4

x+20 = 4x -4 > multiplied out

20 + 4 = 4x – x > moved similar items to same side

24 = 3x

x = 8

**Now we know x, we have to find the sides (ALWAYS GO BACK AND MAKE SURE YOU KNOW WHAT WAS ASKED)**

x -1 = 8 – 1 = 7

4 = 4
