The pentagon are similar drag and drop the answer to correctly complete statment the scale factor is 0.5 1 2 3

A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor 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

Ibelieve the answer would be b.

So don't take my word i'm not exactly a mathematical person but i would assume a. because while selling the soap every month you increase in sells so you would by 11 percent. the you would get the factor 0.89 which if i had to guess would be the monthly profit over 11 probably wrong tho
