If x-8 = 10, then
x= 18.

Statement

Reason

18-8=10

Step-by-step explanation:

If x is 18, the equation is x-8=10. Change the x to a 18 and then subtract as you normally would do. 18-8=10. How to check if you're right? 10+8=18. Switch the signs around and the 10 and 18. Hope this helped a bit!

the answer is 0.071

good luck! : d

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
