Answer: 7x-5
Step-by-step explanation:
Assuming the expression is 21^2 + 13x -20.
(7x-5)(3x+4)
Y = 16.14z ; the constant of proportionality is 16.14. It is called constant of proportionality because it never changes. It remains constant or the same. Whatever the value of z is, y is directly proportional to z by the rate of the constant of proportionality.
