PLEASE HELP, DUE TDOAY

Jayden is remodeling her house by replacing the flooring on the ground floor. She had some leftover materials from a previous project and calculated that the material would allow her to cover an area modeled by the expression 2x2 – 5x + 7. Jayden then purchases some flooring from a home improvement store to cover an additional area modeled by the expression 7x2 + 4x + 1. Which expression represents the total area that can be covered by the flooring?
