Answer:
the coefficient of the 2nd term: - 38
Step-by-step explanation:
V = 2x (4x + 1) (5x - 6)
=(8x² + 2x) (5x - 6)
= 40x³ - <u>38</u> x² - 12x
20+12+15= 32+15 = 47 minutes in total
300 meters per minute
300 * 47 = 14100 meters in total
with this we can see the first race was 4/9 that distance meaning the first race was 6266.6 meters long
14100 - 6266.6 = 7833.3
2/5 of 7833.3 is 3133.32
therefore 7833.3 - 3133.32 will give the distance of the third part of the race
meaning of course the answer is 4699.98 or rounding up 4700 meters for the third race
Answer:
-5/9
Step-by-step explanation:
−4/5 divided by 12
