crucifiedx SG y is proportional to x^n.write down the value of n when(i) ycm^2 is the area of a circle of radius xcm,(ii) y hours is the time taken to travel a distance xkm at a constant speed.
HelloKittyFan SG (3x - 1)(x + p) = 3x^2 + 3xp - x - p = 3x^2 + qx - 2 p = 2 3xp - x = qx3x(2) - x = qx6x - x = qx5x = qx q = 5
crucifiedx SG (3x - 1)(x + p) = 3x^2 + 3xp - x - p = 3x^2 + qx - 2 p = 2 3xp - x = qx3x(2) - x = qx6x - x = qx5x = qx q = 5 thanks alot. =)
