Solvex2 - 8x + 12 =0 for x.
The solutions for x are
and

2 and 6

Step-by-step explanation:

First factor x from the expression

x^2-2x-6x+12=0

x(x-2)-6x + 12=0

Then factor out x-2 from the expression

x(x-2)-6x + 12=0

(x-2)(x-6)=0

When the product of factors equals 0, at least one factor is 0

(x-2)(x-6)=0

x-2=0

x-6-0

And so

X=2

X=6

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.
