Question

(geometry) show or explain all the work on how you got the awnser please and thank you ​

Answer 1

Explanation:

there is not much to explain.

we have a piece of line (LM) that is 8 long.

and then we add another piece of line (MN) that is 9 long.

this is basically the same type of question like "when you have 3 apples, and your mom gives you 2 more apples, how many apples do you have now ?"

for the apples it is 3+2 = 5.

for the lines here

LN = x = LM + MN = 8 + 9 = 17

that's all.
