Answer:
8 times 4= 32-7=25
Step-by-step explanation:
To find a speed in miles per hour, we need to divide a number of miles by a number of hours.
We are given 48 miles, so we already have a number of miles.
We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.
1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours
speed = distance/time = 48 miles / 1.2 hours = 40 mph
Answer: The fourth choice, 40 mph.
Step-by-step explanation:
(x² - 3x + 4) (-2x² + 4x - 1)
Start by distributing the first term into the second:
-2x² (x² - 3x + 4) + 4x (x² - 3x + 4) - 1 (x² - 3x + 4)
Now distribute each term:
-2x⁴ + 6x³ - 8x² + 4x³ - 12x² + 16x - x² + 3x - 4
Combine like terms:
-2x⁴ + 10x³ - 21x² + 19x - 4
