65 miles per hour divided by 60 minutes is 1.08 miles a minute.
10 miles divided by 1.08 is 9.26 minutes rounded to 9
50 miles per hour divided by 60 minutes is .83 miles per minute.
10 miles divided by .83 is 12.04 minutes rounded to 12
12 - 9 = 3 fewer minutes
Answer: 2x³ + 2x² + 36
Working:
= (2x + 6) × (x² - 2x + 6)
= 2x³ - 4x² + 12x + 6x² - 12x + 36
= 2x³ -4x² + 6x² +12x -12x +36
= 2x³ + 2x² + 36
