How many solutions does the equation have? 2(x+3)=2x+6

Me. i can't figure out this question. give an explanation too. .

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)
