(2 x n - 2 x 6)
(2n - 2 x 6)
2n - 12
Answer:
Look below
Step-by-step explanation:
I'm going to use B as my example to explain: B (-3,4)
You are going to need to draw a coordinate plane. When drawing the X axis, you want the highest X point to be 6 due to the fact that that is your highest x value. Then you want the lowest X point to be -6. Same will apply with the Y axis.
Next you are going to put a point in the middle of the plane which is called the origin (0,0).
Going from the origin, you want to follow the x axis the get to -3 which will be going left since its negative. Then since the Y axis is vertical, you are going to go up 4 times since the 4 is positive.
Then start from the origin for the next point being C (-5,4), Remember to always start from the origin.
The answer is C because when you have similar radicals, you subtract the whole numbers. In this case 3 square root of 2 minus square root of 2, is doing 3 - 1 = 2.
2 square root of 2
4 hundred thousand are in it simple!
