c) The sides of a triangle are x cm, (x - 5) cm and (x + 3) cm long. If the perimeter is 25 cm, find the length of the three sides. x+x-s+x+3=4s x+x+x-5+3 = 25 3x - 2 = 25 3x = 27 x = 오 d) I think of a number. If I subtract 9 from it and multiply this difference by 4 the result is 32. What is the number I thought of? x-9x4 = 32 Y 19-32 X=17
