(x^2 + 3)(5x + 9)
5x^3 + 9x^2 + 15x + 27
Answer:
98
Step-by-step explanation:
Total distance 272 miles.
Total speed (when travelling toward each other) = 75+95=170 mph
Time to meet = 272/170=1.6 hours
Answer:
30 min
Step-by-step explanation:
She takes 45 minutes to run 6 miles.
Lets simplify this. If we divide by 3, then we know that:
She takes 15 minutes to run 2 miles.
Therefore, to find the amount of time it takes to run 4 miles, we just multiply 15 by 2.
Therefore it takes her 30 mins to run 4 miles.
