Answer:
Because -$10 is basically nothing because it is negative you don't have ten dollar, but a debt of $10 means you have it which is why it is greater than -$10
1. (x + 6)(x + -12)
2. (x + 10)(x - 10) = x² - 100
3. (x - 6)(x + 17) = x² + 11x - 102
4. (-x + 8)(x - 5) = -x² + 13x - 40
5. (x + 13)(x + 8) = x² + 21x + 104
6. (x + 2)(x + 7) = x² + 9x + 14
Answer:
A hamburger costs $2.45.
Step-by-step explanation:

X represents the price of one hamburger.
