She needs to earn at least 84 to buy the mp3 player
earnings=earningsperhour times numberofhoursworked
earnings per hour=12 dollars
number of hoursworked=h
therefor
earnings=12 ties h or12h
earnings is at least 84
earnings is greater than or equal to 84
earnings<u>></u>84
12h<u>></u>84
solve
12h<u>></u>84
divide both sides by 12
h<u>></u>7
she needs to work at least 7 hours

Answer:
(x - 6)(x + 3)
Step-by-step explanation:
Consider the product of the factors of the constant term which sum to give the coefficient of the x-term
product = - 18 and sum = - 3
The factors are - 6 and + 3, hence
x² - 3x - 18 = (x - 6)(x + 3)
