You can figure out the precise distance between these two points by using what you know about right triangles: that the sum of the squares of the legs equals the square of the hypotenuse.
Here's how. First, plot both of these points (-2, 5) and (12, -1) on a piece...
Well that depends. If you're rounding to the nearest ten, it would be ten: (995 - 1004). If you were rounding to the nearest hundred, there would be a hundred, to the nearest 1000 there would be a thousand.
Hey there. Since you are squaring it, you multiply it by itself. Thus it's:
(2x + 4)(2x + 4)
You need to FOIL it. You know, First, Outside, Inside, Last:
4x2 + 8x + 8x + 16.
Then combine like terms:
4x2 + 16x + 16.
Shake a leg...
