now is this actually possibe?
is it soemthing like -
1000/ no. sides = side lengths
360 / no.of sides equals exterior angles.

and can you work out the area from this?
is there a formula i can apply to get the area of regular 4, 5, 6, 7, 8, 9, 10 (etc) sided shapes?

a.)Hypothesis:
b.)Conclusion:
c.)Converse:

6.)Name the property of algerbra or of congruence which justifies each statement.
a.)If x+3=18, then x=15 ____
b.)If m angle P+m angle S+m angleT=180 and m angleT = 40, then m angles P + m angle SS + 40= 180.

Could someone please explain step by step how I could solve the following equation by completing the square: k^2-8k+12=0 . I'm getting stuck when it comes to factoring it out. So far I have k^2-8k+12=0
k^2-8k=-12
k^2-8k+16=-12+16
(k+4)^2=4
This is where I get stuck at do I need to further square k+4. I have the answer to the question but the answer I figures out doesn't match what the correct answer is supposed to be.
