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 it's width is 2 ft.
1 answer:
Let width = x, then length = 3x - 2.
So we have area = width * length = x * (3x + 2)
A = 3x² + 2x
Now we need to find A(2) = 3 * 2² + 2 * 2 = 16ft²

This is a proportion problem
3/10= 12/x
Now cross multiply and divide
12 x 10= 120
120/3= 40
Answer is 40
- m<2=7(6)-14=42-14=28[/tex]
This is just here for the 20 character limit but the answer is in the picture.
I think it might be f^-1 (x) = x/2 - 3/2
I hope this helps!
