and the circle has radius
, then the arc has length
such that

where

Answer:
32 red
28 white
20 blue
Step-by-step explanation:
.40 x 80 = 32 red
.35 x 80 = 28 white
.25 x 80 = 20 blue
The totals have to equal the total number of strands.
= <span>(-8x - 9)(-9x2 + 7x - 9)
= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81
= 72x³ + 25x² + 9x + 81
In short, Your Answer would be: Option D
