Acollege is planning to construct a rectangular parking lot on land bordered on one side by a highway. the plan is to use 680 feet of fencing to fence off the other three sides. what dimensions should the lot have if the enclosed area is to be a maximum?

What could explain what happened when the time was equal to 120 minutes

Use the distributive law to multiply. 3(4x + 5y + 6)
