Answer: -4x^2 + 8xy - 20y^2 + 12
Step-by-step explanation:
-4 (x2 - 2xy + 5y2 - 3)
-4(x^2) = -4x^2
-4(-2xy) = 8xy
-4(5y^2) = -20y^2
-4(-3) = 12
Answer: 1 hour is equal to 46 miles 2 hours is 92 miles and 20 hours is 920 miles
Step-by-step explanation:
92/2 = 46 miles
46 x 2 = 92 miles
46 x 20 = 920
It is 15, as 20 is only a factor of 60 and not 75.
