You know a right triangle With 3 legs and 4 units has a hypotenuse of 5 units. Use algebra to show that any right triangle with sides 3n and 4n has a hypotenuse of 5n

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

answer is because 4×10=40

and 98×4= is 392

40,392

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.
