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

Ch5.6 #15 As before – all are similar so I will pick the harder one. Givens AB = CD AB = 9(x-2) CD = x + 3(x+5) Therefore, 9(x-2) = x + 3(x+5) Now multiply...
For problem 5.6, parts a-d are all pretty much the same. Here I will do part d) since a hair more complex. The steps the same for the others. Since AB = CD,...
