Joe is 72 inches tall and has a 108 inch shadow at the same time martha has a 96 inch shadow how tall is martha

64 inches

Step-by-step explanation:

Given :

(Joe's height / Joe's shadow) = (Martha's height / Martha's shadow)

Let Martha's height = h

72 in / 108 in = h / 96 in

Cross multiply :

108 * h = 72 * 96

h = (72 * 96) / 108

h = 6912 / 108

h = 64 inches

Martha is 64 inches tall.

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
