Please help look at link
We looked; now what is the question?
sorry what is the perimeter
(11x-7)/(2x^2-2x)
Perimeter is distance around. Add 'em all up.
Perimeter = sum of lengths of all four sides 3 3 2 4 P = --- + ---- + ----- + ------ x 2x x+1 x² - 1 3 3 2 4 P = --- + ---- + ----- + ------------- x 2x x+1 (x + 1) (x - 1) 3[2(x+1)(x-1)] + 3[(x+1)(x-1)] + 2[2x(x-1)] + 4[2x] P = ----------------------------------------------- 2x (x+ 1) (x - 1) 6(x² - 1) + 3(x² -1) + 4x(x - 1) + 8x P = --------------------------------- 2x (x² - 1) 9(x² - 1) + 4x² - 4x + 8x P = ----------------------- 2x (x² - 1) 9x² - 9 + 4x² + 4x 13x^2 + 4x - 9 p = ------------------ = ---------------- 2x^3 - 2x 2x^3 - 2x
pls check if any more simplification is possible......
Correction to my earlier answer: (13x-9)/(2x^2-2x)
