Answer 1

F

Explanation:

If u add 6 and 4 together then ya get 10. If ya add those two then u will see that the line is not much longer then line x.

Answer 2

since they're similar, let's use the proportions of their sides

`\cfrac{NO}{LK}~~ = ~~\cfrac{MN}{JK}\implies \cfrac{x}{15}~~ = ~~\cfrac{6}{9}\implies \cfrac{x}{15}~~ = ~~\cfrac{2}{3}\implies x=\cfrac{30}{3}\implies x=10 \\\\[-0.35em] ~\dotfill\\\\ ~\hfill \stackrel{\textit{perimeter of MNO}}{4~~ + ~~6~~ + ~~10~~ = ~~20}~\hfill`
