A. The solution is nonvlable because the percentage filled cannot be negative. B. The solution is nonviable because the time cannot be negative. Oc. The solution is nonviable because the time cannot be partial minutefly D. The solution is vlable.

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

i think the answer is a p = 78

step-by-step explanation:

there are 6 sides of a hexagon, multiply 13 x 6
