Polynomial that represents the total volume of this box

Hello!

To find the volume you multiply all the sides

(x)(x - 4)(x - 2)

x * x = x^2
x * -2 = -2x
-4 * x = -4x
-4 * -2 = 8

x^2 - 6x + 8

x * x^2 = x^3
x * -6x = -6x^2
x * 8 = 8x

The answer is A) x^3 - 6x^2 + 8 

Ibelieve the total for the tip could be $21.90

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
