Answer:

15 and 27 are composite

Step-by-step explanation:

prime numbers only factor into 1(x) and x(1)

13 = 1(13), 13(1)

15 = 1(15), 3(5), 5(3), 15(1)

17 = 1(17), 17(1)

27 = 1(27), 3(9), 9(3), 27(1)

hope this helps

How do you simplify this equation
dezoksy [38]

\bf \cfrac{\quad2-\frac{4}{x+2} \quad }{5+\frac{10}{x+2}}\implies \cfrac{\stackrel{LCD~of~x+2}{\frac{2(x+2)-4}{x+2}}}{\stackrel{LCD~of~x+2}{\frac{5(x+2)+10}{x+2}}}\implies \cfrac{\stackrel{distributing}{\frac{2x+4-4}{x+2}}}{\stackrel{distributing}{\frac{5x+10+10}{x+2}}}\implies \cfrac{\quad\frac{2x}{x+2} \quad }{\frac{5x+20}{x+2}} \\\\\\ \cfrac{2x}{\underline{x+2}}\cdot \cfrac{\underline{x+2}}{5x+20}\implies \cfrac{2x}{5x+20}\implies \cfrac{2x}{5(x+4)}
