x²-x 11. Given *-1 = (x+1)(x-1) = (x+3)(x==== 1. Is the process of simplifying the rational *(x-1) *(x-11 expression correct? x²-1 A. Yes, because is equivalent to which is equal to 1. Yes, because the process followed the steps in simplifying rational expression. C. No, because dividing out of the common factors were done incorrectly. D. No, because the factors of the numerator and denominator are incorrect. x2-x 12. Suppose you are painting a square whose side measures s long. What is the ratio of the perimeter to the area of the wall in simplest form? A.2 C. B. 2s 13. Suppose the city circle has a radius r. What is the ratio of the circumference to the area of the city circle in simplest form? A.1 C. 2 1 를 *+2 14. Is the rational expression in simplest form? x²-4x+4 A. Yes, because the numerator and the denominator have no common factor other than 1. B. Yes, because the numerator and the denominator are in simplest form of a polynomial expression, C. No, because the numerator and the denominator have different degrees. . No, because the numerator and the denominator were not factored completely.
