Below is the linear programming for the Shortest Path Problem. Considering the second contraint in the mathematical model :
∑ixji−∑ixij=0∀j≠s, j≠t
What is the logic behind this contraint?
A. To make sure there is only one solution
B. To make sure that the path is connected between the nodes
C. To make sure the variable stays binary
D. This contraint is redundant and not necessary

step-by-step explanation:

two pairs of adjacent sides are of equal length. this implies that one diagonal divides the kite into congruent triangles, and so the angles between the two pairs of equal sides are equal in measure. it also implies that the diagonals are perpendicular.

3.07*10^-4

move the decimal 4 places to the left

.000307

this would be 35. 35 + 5 = 40. you take the known constant and subtract by the answer of the equation and you get y.
