Question

Assume that the area of the blue region is 100 units squared. Which equation represents this?
A. x^2-15x+54=0
B. x^2-15x-46=0
C. x^2+15x+54=0
D. x^2+15x-46=0

I don't even know where to start. Can anyone explain this to me?

Answer 1

Could we see the blue region first?

Answer 2

that's the thing.... there is now blue region... there wasn't a picture

Answer 3

I just took it as what the equation represents is 100 units squared, and im just really confused on that, how to find out which equation represents it I mean

Answer 4

That's interesting. Which lesson is this problem for then? Using quadratic formula?

Answer 5

No, I know how to use the quadratic formula, its and Apex highschool class and the lesson is on quadratic equation

Answer 6

@agent0smith Is this even possible?

Answer 7

@campbell_st

Answer 8

lol you can't answer this question without a pic.

I'd guess it's either A or C, since both of those factor:

A. x^2-15x+54= (x - 9)(x-6)

C. x^2+15x+54= (x + 9)(x+6)

Answer 9

apparently it was D, I got A or C too, but I was wrong I guess... It was Rigged, I swear

Answer 10

Well it's definitely rigged. You can't refer to a "blue region" and not have a diagram.

Answer 11

That's What I thought!! I was like cool I can figure this out I think.... but then there wasn't a picture and I got totally messed up and confused, but whatever
