Which statement is assumed to be true in euclidean geometry?

a.) three points on the same line lie on exactly one plane.
b.) a plane contains at least three points that do not lie on the same line.
c.) a plane contains at least two points that do not lie on the same line.
d.) three points on the same line never lie on the same plane.

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
