The answer is D. I graphed it on Desmos Graphing Calculator and I've linked the screenshot.
Hope this helps :)
So, to do this, all you need to do is add up all the values, and then, with that number, divide by how many values are given.
150+165+165= 480
480/3= 160
2x^2+(6-1)x-3
2x^2+6x-x-3
2x(x+3)-1(x+3)
(2x-1)(x-1)
Writing an equation would be most helpful, but depending on the situation drawing a diagram or reading a table could work better.
