If r(x) = 3x – 1 and s(x) = 2x + 1, which expression is equivalent to
(r/6)(6)?

225x²+4=0

225x²=0-4

225x²=-4

x²=-4/225

x=±√-4/225

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

step by step explanation: when u removing the parentheses and combined them that would be : x+3y-x-y=2y
