What’s an example of this right and how do we know this?

The factorization of 8x3 -125 is (2x-5)(jx2 +kx+25)

Just tell me how to set up the equation.

1. writing an equation for an exponential function by 2. a piece of paper that is 0.6 millimeter thick is folded. write an equation for the thickness t of the paper in millimeters as a function of the number n of folds. the equation is t(n)= 3. enter an equation for the function that includes the points. (-2, 2/5) and (-1,2)
