Which of these is the statement of the zero product rule? O A. If a·b = 0, then a = 0 and b= 0.
O B. If a• b = 0, then either a = 0 or b = 0, or both.
C. Ifa:b= 0, then a = 0.
D. If a·b = 0, then either a = 0 or b = 0, but not both.

If 10 men take 18 days to mow 60 acres of grass, how long will 15 men take to mow 80 acres?

The label on the car's antifreeze container claims to protect the car between ? 40°c and 125°c. to convert celsius temperature to fahrenheit temperature, the formula is c = 5 over 9 (f ? 32). write and solve the inequality to determine the fahrenheit temperature range at which this antifreeze protects the car. ? 40 > 5 over 9 (f ? 32) > 125; ? 40 > f > 257 ? 40 < 5 over 9 (f ? 32) < 125; ? 40 < f < 257 ? 40 < 5 over 9 (f ? 32); ? 40 < f 5 over 9 (f ? 32) < 125; f < 257
