Hello all. My first post here and I hope you will be able to help me out. I am an undergrad student. I have only a few classes left and will be graduating with honors, providing I don't fully drop the ball in math. I have to take two math classes, college mathematics 1 and 2. Once these classes are done, I am all but finished.
I use several tutoring tools and use the examples and tutorials given, but I am having a hard time associating some questions with the examples I've practiced.
Here is one set of problems I am working on. Any help would be appreciated. Thank you in advance.
Perimeter of a rectangle. A rectangle has a fixed width and a variable length. Let P represent the perimeter and L represent the length. P=28 inches when L=6.5 inches and P=36 inches when L=10.5 inches. There is a linear equation that expresses P in terms of L.
a) Find the equation.
b) What is the perimeter when L=40 inches?
c) What is the length when P=215 inches?
d) What is the width of the rectangle?
