B because 2 and 1/3 is 7/3 as an improper fraction times 4 is 28/3 and as a mixed number it is 9 and 1/3
(3x³ - 7x² + 12) - (3x³ + 6x² + 10x)
(3x³ - 3x³) + (-7x² + 6x²) - 10x + 12
-x² - 10x + 12
Answer:
17/13
Step-by-step explanation:
r(6) = 3(6) - 1 = 17 and s(6) = 2(6) + 1 = 13.
Then (r/s)(6) = 17/13.
Im pretty sure the answer is t = 50 + 91.40n
