Hello! To find out how many inched the hallway is, you first need to know how many inches are in a yard. You need to find the operation that will be needed for this problem, and I'm assuming you don't know, what you want to do is ask yourself,"What am I trying to find? Wold this best be accomplished with subtraction or division, or multiplication or addition? Am I looking for what the difference between two, or how many items are needed for even groups? Do I want to find out how long something will be when added to something else, or multiplied?
I hoped this helped! If you have any further questions pertaining to this problem, feel free to shoot me a message or another question! Good luck :)
Letter C is correct. When the function is even, (all powers are even) both ends will go in the same direction. In this case since the leading coefficient is negative, both ends will go down.
