A dilation with a scale factor of 1/2 is applied to the three sides of triangle abc to create triangle a'b'c'. The side lengths of triangle abc are: a = 4ft, b = 3ft, c = 5ft. What are the lengths of the sides on the new triangle a'b'c'?.

It depends on the subject for me. some exams are easier than others so i usually go through it and answer questions i know based on my general knowledge, then double check after. going through the lesson can a lot  because the exams can be  very lesson-specific, but sometimes they are ridiculously long so a lot of people don't take the time. i did find that, when i went through the lessons, i was making 100's on my exams vs strictly using + the internet and  i make 90's.
