Answer:
(11x - 9y) (121x² + 99xy + 81)
Step-by-step explanation:
Difference of cubes
∛1331x³ = 11x = a
∛729y³ = 9y = b
(a³ + b³) = (a + b) (a² - ab + b²)
(a³ - b³) = (a - b) (a² + ab + b)
(1331x³ - 729y³) = (11x - 9y) (121x² + 99xy + 81)
25 x² - 10 x = 0
5 x ( 5 x - 2 ) = 0
x = 0 and
5 x - 2 = 0
5 x = 2
x = 2: 5
x = 2/5
Answer: B ) x = 0 and x = 2/5
Answer:
so the answer is 3/2x

Is that all the information privided? Im tring to figure it out but I feel like im missing something.
Twelve runners because if you take three-fourths times four you will get twelve-sixteenths. and each runner runs one-sixteenth so it is twelve.
