If Pete can paint a wall in p hours, then in one hour he can paint 1p of the wall. It would take Penelope 3 hours longer than Pete to paint the wall, so in one hour she can paint 1p+3 of the wall. Add the rational expressions 1p+1p+3 to get an expression for the part of the wall Pete and Penelope would paint in one hour if they worked together.

Erik is building a cubby bookshelf, that is, a book shelf divided into storage holes (cubbies) instead of shelves. He wants the height of the bookshelf to be x^2 - 11x - 12 and the width to be x^2 + 3x + 2. Each cubby hole in the bookshelf will have a height of x + 2 and of width of x - 12. Multiply the rational expressions from Step 1 and Step 2 to obtain a rational expression that gives the total number of cubbies in the entire bookshelf.
