Answer:

Step-by-step explanation:

Percy is not correct because he applied the zero product property to a factored expression that was not equal to 0. He should have subtracted 12 from both sides to get x2 + 7x = 0 before factoring. The correct solutions are 0 and -7.

Answer:

B. x ≥ 1

Step-by-step explanation:

Step 1: Subtract 6x from both sides

Does the average person live for at least 1,000,000 minutes?
irakobra [83]
Convert to hours, then days, then years
60 minutes per hour
1000000/60=50000/3=16666.7 hours

24 hours per day
16666.7/24=694.4 days
365 days per year
694.4/365=1.9

the average person lives at least 1.9 years
maybe, I guess
