F(x) = x^2 - 5x+8, g(x) = x^2-4

Find g(x)-f(x)

1. are the triangles similar and if so why? what is the value of x? show your work.

The population of a small rural town in the year 2006 was 2,459. the population can be modeled by the function below, where f(x residents and t is the number of years elapsed since 2006. f(t) = 2,459(0.92)

1) prove that 731^3−631^3 is divisible by 100 2) prove that 99^3−74^3 is divisible by 25
