Answer:
Step-by-step explanation:
f(x) = −3(x² - 2x + 1) + 3
f(x) = −3x² + 6x - 3 + 3
f(x) = −3x² + 6x
** The above answer is written in reverse, which is the exact same result.

The answer is independent
Assuming that there are N lanes and runners are running in the middle of each lane,
width of each lane = (1/N) [m]turning of first lane = π×(R+(1/N)×(1/2))
turning of second lane = π×(R+((1/N)×(1/2))+(1/N))
you can get the difference in turning lane simply by subtracting turning of first lane from turning of second lane.
If i worked the problem correctly, it should be π×(1/N) meter difference between each lane
Q=(c+d)/2
Multiply both sides by 2 to get rid of the 2
2×q=(c+d)
Subtract c from both sides to get rid of the c
2×q-c=d
Flip the equation around
d=2×q-c
Answer:
Option C is the correct answer
Step-by-step explanation:
C. Multiply both sides of the equation by 20
