Answer:
x=3
Step-by-step explanation:
14=7(2x-4)
14/7=2x-4
2=2x-4
2x=2+4
2x=6
x=6/2
x=3
------------
14=7(2x-4)
14=14x-28
14x=14+28
14x=42
x=42/14
x=3
Answer:

where where a and b are the legs and c is the hypotenuse.
Let a=6ft, b=21ft and c=23ft, then




which is not possible, therefore the given triangle is not right triangle because it does not satisfy the Pythagoras theorem.
What is proportional?
