Answer:

Step-by-step explanation:
observe by inverse definition of a function

Okay so you have to do 5 times 10 then you will have to do 8 time 8 times 40 so after you get your answer you would do the ratio 50 to 320
50:320
A defined terms can be combined and form with the undefined terms to complete the definition of the term. A vertex for example, it is form when two lines are meet to each other or there would be an intersection of two lines. I hope you are satisfied with my answer and feel free to ask for more
Because most of them keep on going for infinite. For example,

is an irrational number that goes on forever 3.14159 etc etc etc
