Answer:
x^2 + y^2 + 2xy
Step-by-step explanation:
Use the FOIL method.
Multiply the first terms: x•x=x^2
Multiply the outer terms: x•y=xy
Multiply the inner terms: y•x=xy
(alphabetical order)
Multiply the last terms: y•y=y^2
Combine like terms:
x^2 + y^2 + xy + xy
x^2 + y^2 + 2xy
If you add $15 + $27 because that's how much it costs for each student, you get $42. Then you divide $714 by $42, you get 17 and that's how many students are in the class this month.
