Question 546819: A rectange shed covers 300 feet of ground. It is 6 feet longer than it is wide. What is the width of the shed to the nearest tenth of a foot?
This is what I tried:
x = width
x + 6 = length
Area of a Rectangle = 300
What I set up: 300 = x(x + 6)
Which then I got: 300 = x^2 +6x
That is all I could figure out.

What you've done so far is good!
Now you need to solve the resulting quadratic equation for x (the width).
Use the quadratic formula: where: a = 1, b = 6, and c = -300.
which evaluates to:
or Discard the negative solution as the width (x) must be a positive value.
The width is 14.6 feet (to the nearest tenth of a foot).
