x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

$x = \frac{-b+/-\sqrt{b^2-4ac} }{2a}$     (+/- is this ±)

plug in the numbers into the variables

$x = \frac{-3+/-\sqrt{3^2-4(1)(7)} }{2(1)}$

$x=\frac{-3+/-\sqrt{9-28} }{2}$

$x=\frac{-3+/-\sqrt{-19} }{2}$

$What is the solution to this equation? x^2+3x+7=0$

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.

Sorry i meant b in the other question
$Looking at def, which statement below is true? i think the answer is b$
