Question 1050184: Please help with this problem.
A rectangle parking space is m feet wide and n feet long. In the new design for the parking lot, each space will have its width increased by 1 foot and it's length increased by 20%.
A. Write a polynomial to represent the area of the new parking space.
B. Shoshanna says that the area of each new parking space is 20% larger than the area of the old parking space. Is this correct? Use the polynomial you wrote in part A to explain why or why not.
Thank you so much in advance, please show all work and explain how you got your answer.

Question 1050236: I need help on writing polynomial expressions of the volume and surface areas of some figures. I've already tried what I can (we didn't cover this well in class so I'm lost).
1) Rectangular prism. Length = 3b; width = b+1; height = b-5
2) Cone. Height = 12n; radius = n-2
3) Pyramid. Lenght = k-2; width = 2k+3; height = 3k
4) Rectangular prism. Length = 2x+1; width = x+3; height =2x
5) Cylinder. Height = w+3; radius = w-1
6) This last one is a 3D triangle...forgot what it's called. Height = 2y; width = 2y+1 ; length = 3y; the sloping thing is y+3
Please help, I really need to figure out how to do this as we didn't do this well in class and I don't understand.
