Rewrite the function by completing the square. f(x)=x^2+14x+8

f(x)=(x+__)^2=__

And solving we got:

And we can reorder the terms we got:

And that would be the equivalent expression for the problem

Step-by-step explanation:

For this case we have the following function given:

And we can complete the square adding the middle of 14 squared and subtracted before like this:

And solving we got:

And we can reorder the terms we got:

And that would be the equivalent expression for the problem

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.

by definition, an arc subtended by a central angle of some given measure has the same measure. so .
