factor the following polynomial completely.
-x ^2 y^2 + x 4 + 9y^2 - 9x^2
(x - 3)(x - 3)(x + y)(x - y)
(x + 3)(x + 3)(x + y)(x - y)
(x + 3)(x - 3)(x + y)(x - y)

For f(x)=2x+3 and g(x)=x^2- 8 find (f+g) (x)

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).

Acolony contains 1500 bacteria. the population increases at a rate of 115% each hour. if x represents the number of hours elapsed, which function represents the scenario? f(x) = 1500(1.15)" f(x) = 1500(115) f(x) = 1500(2.15) f(x) = 1500(215)
