The square root of 9 is 3, and 3 divided by 34 and multiplied by 5 is <span>0.44117647058. You would have to use a calculator for this and that's what I did. I hoped I helped!</span>
Answer: All polygons follow a rule that the sum of their exterior angles will equal 360 degrees.

Now completing the square.

(x+5)² = 16 is the rewritten equation... For first question btw.
For the solutions to the equation -

x = -1,-9 is the solution, for the second question.
Answer:
A.) = 6
If RE = 12, then RD = 6
B.) = 10
If BR = 10, then BE = 10
C.) = 16
If BD = 8, then BK = 16
D.) = 30*
<m9 = 90*, and <m2 = 60*, so add them and subtract from 180*, you are left with <m1 = 30*
E.) = 60*
If <m2 = 60*, then <m3 = 60*
F.) = 90*
It`s a 90* angle because BK and RE and perpendicular
G.) = 60*
If <m1 = 30*, then multiply by two because it is symmetrical
I would show all my work but you seem to be in a rush. Hope this helps!
