Which statement is correct?

*Image below*

Which expression is equivalent to the expression below? (6c^2 + 3c) / (-4c + 2) / (2c + 1) / (4c - 1)a. 3c(2c-1) / (2c + 1)b. -3c(2c-1)^2 / (2c + 1)^2c. 3cd. -3c(just took the test its d. -3c)

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
