Question

Kayla worked 3x + 6 hours this week. She earns x - 2 dollars per hour. Write a polynomial expression that represents the amount Kayla earned this week

Answer 1

Answer:

3x^2-12

Step-by-step explanation:

money she earned = work hour x hourly earning

(3x+6)(x-2)=3x^2-6x+6x-12=3x^2-12

Answer 2

Answer: 3x² - 12

Step-by-step explanation:

(3x+6)(x-2) = (3x*x) + (3x*-2) + (6x*x) + (6x*-2) = 3x² + 6x - 6x - 12 = 3x² - 12
