What is the scale factor of the map (map is in the picture)

1unit=557

  1 unit = 557 miles

Step-by-step explanation:

The scale shows that 1 unit corresponds to 557 miles. Since we don't know the length of 1 unit, the best we can say is that the scale is ...

  1 unit : 557 miles

or

  (1 unit)/(557 miles)

step-by-step explanation:

my butt

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
