Im Making up work and cant figure this out.

Measures of the angle of r, 31 s (x+4) t (3x+9)

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)

Simplify the following expression 48^1/2
