Answer:
4n +28
Step-by-step explanation:
Tommy's purchases add up to ...
4n +10 + 18 = 4n +28

↝ Form into
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula

↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝

Therefore, the answer for Complex Number System is (5±√7i)/2
