Step-by-step explanation:
Y = x² - 6x + 14
y = x² - 6x + 3² - 3² -14
y = (x - 3)² - 9 - 14
y = (x - 3)² - 23
------------------------------------------------
Answer : y = (x - 3)² - 23

It will take 20 hours to completely fill the pull with 920 gallons of water. Because they are asking HOW MANY MORE it would take 15 more hours. How I got to that answer: Divide five from 230. You’ll end up getting 46 which means the pull is being filled up 46 gallons per hour. Now you’re going to want to divide 46 from 920. That’s when you’ll get 20.
