Can you guys help me figure this out

Each of the walls of a room with square dimensions has been built with two pieces of sheetrock, a smaller one and a larger one. the length of all the smaller ones is the same and is stored in the variable small. similarly, the length of all the larger ones is the same and is stored in the variable large. write a single expression whose value is the total area of this room. do not use any method invocations.

Josephine has a great garden with and area of 2x2 + x - 6 square feet

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
