the pressure, p (in lbs/in2) that a 160-pound person's shoe experts on the ground when walking varies inversely with the area, A (in in2), of the sole of those shoes. When the shoes have a sole area of the 40 in2, the pressure is 4 lbs/in2. Find an equation that relates to these variables.

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.

the answer is d on edge

step-by-step explanation:

irrational, cannot

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
