6. The length of a rectangle is 3 in more than its width. The perimeter of the rectangle is 30 in.
a. Define a variable for width
b. Write an expression for length in terms of the width.
c. Write an equation to find the width of the rectangle.
d. Solve your equation.
e. What is the length of the rectangle?

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
