Alawn service charges 17 dollars per lawn. if the lawn service earns 187 dollars in a day, write an equation to represent the number of lawns the company serviced.

Let x be the number of lawns they serviced. Since they made 187 off of the number of lawns serviced, and they make 17 dollars per lawn, we have the equation:

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form

chad should not have included the values (1, 2) and (3, 6) because that would mean he only had half a healing card.
