Question 517745: Please help this is all one problem and I am struggling with it.
Write a function rule for the area of a rectangle with a length of 2 ft less than three times its width. What is the area of the rectangle when its width is 2 ft?

Start with the formula for the area of a rectangle:

But the length, L, is given as:
"...length is 2ft. less than three times its width." Substitute this into the area formula.
Simplify.
This is the function you need.
When the width is 2ft., then W = 2, so substitute.

So when the width is 2ft., the area is 8sq.ft.
