Frustrating word problems

Hello, I am new to these forums. After hitting a wall on my take-home quiz, I am on the hunt for some assistance. Our professor told us we can use any means necessary to get help, so I am doing just that! Always been terrible at word problems, algebra in general for that matter. Have two problems here that left me with nothing but a blank paper and a nasty migraine!

1. The area of a rectangle is 80 meters^2 (squared). The length is six more than twice its width. Find the length and width.

2. The profit *P*, generated for a video store is given by the equation p = x^2 - 15x - 50, where *X* indicates the number of videos sold. How many videos must be sold for the profit to be $200?

Thanks in advance!
