Solve the rational equation:
3x/x+1 + 2x/x-2 = 4x^-4/x^-x-2

Don't know how to find x given these segment lengths

Which shows the graph of the solution set of 3y – 2x > –18?

Suppose a laboratory has a 30 g sample of polonium-210. the half-life of polonium-210 is about 138 days how many half-lives of polonium-210 occur in 1104 days? how much polonium is in the sample 1104 days later? 9; 0.06 g 8; 0.12 g 8; 2,070 g
