The length of a side is 18.
Here is my work attached:
C. $135, 1/4 of 60 is 15 and add that on top of 60x2
To solve these problems you need to use the quadratic formula which is listed below.

So, if you take #2.
The

has a 1 in front of it. The x has a -3 in front of it. The last number is also -3. So:
a = 1
b = -3
c = -3
Then you can plug all of these into the equation and simplify. Which gives you:
