"The lines of reflection are parallel to the sides of the polygon" is the statement that is true about the lines of reflection for the polygon that will map the shape onto itself. The correct option among all the options that are given in the question is the third option or option "C". I hope that the answer has helped you.
3x+2y=6 is most likely your answer since the slope would be -3/2 and the y intercept would be 3. plus the graph seems to be going down at a slower pace
12. (x-√3)(x+1) = x² + (1-√3)x - √3
13. (x+2)(x²+4) = x³ + 2x² + 4x + 8
14. (3x³ + 6x² - 5x + 12) ÷ (x-3)
= [(x - 3)(3x² + 15x + 40) + 132 ] ÷ (x-3)
Quotient = 3x² + 15x + 40
Remainder = 132
