2x^4 + 8x^3 - 15x^2 + 14x - 3
i think this is the answer. hope this helpss

now, a line perpendicular to that one, will have a "negative reciprocal" slope, thus
Answer: 45.24
Step-by-step explanation:
60 minutes is an hour , you haven't given out what the 15, 30 and 60 are , and the 1 , 2 and 4 are(minutes or hours?)
