Which piece of information is pull prove a parallelogram is not a rectangle A. The diagonals are congruent

B. Of the angles, 2 measure 100, and 2 measure 80

C. The consecutive angles are supplementary

D. The opposite sides are congruent

D. The opposite sides are congruent

constant of proportionality = 3 and the equation is c = 3p.

step-by-step explanation:

c = kp   where c = amount of caffeine in mg., p = oz of pepsi and k is the constant of proportionality.

substituting the values given:

24 = 8k

k = 3.

the same value of k will be obtained if we substitute the other given values.
