Suzie’s flower shop estimates that supplies costs for one month will be given by the polynomial 5x2 + 4x – 7. She estimates that utilities costs for one month is given by 8x + 8. Find and simplify an expression that would estimate Suzie’s total costs for one month.
Just add the two costs:
5x^2 + 4x - 7 + 8x + 8 =?
