A scale factor<span> is a number which </span>scales<span>, or multiplies, some quantity. In the equation y = Cx, C is the </span>scale factor<span> for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. so the scale factor is 2, because the one side of the pentagon became 2</span>
i think it' =-8abc(a+b-c)
