Iwill take exam tommorrow so, what shall i do the day before start exam to score best mark?

You can:

1. Go to bed early enough so when you wake up in the morning you're energized.

2. Look over your notes. If you've studied a lot, just ask someone to ask you questions about what you've learned. Then go back and try to solve a couple problems.

3. Eat a good breakfast, (though that's the day of the exam, it could help you feel energized and to help you feel like you know what you're doing.)

4. GET OFF THAT ELECTRONIC! That will just distract you, so put it away until tomorrow.

5. Tell yourself that you CAN do this, and you won't fail.

6. Prepare some fidgets if you get fidgety during the exam.

7. Prepare supplies. (i.e. freshly sharpened pencils, a calculator, anything you may need.)

8. Sit in a quiet place for a couple minutes and write down what thoughts might weigh you down and dampen your confidence tomorrow during the exam. Once you're done, rip up the paper and throw it in the recycle bin. Forget those thoughts and throw them in your mental trash can.

GOOD LUCK ON YOUR EXAM!

i'm pretty sure it's 477,585,296, but perhaps my math is incorrect.

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.
