Mathwords.com gives this definition of “scale factor”: The ratio of any two corresponding lengths in two similar geometric figures. You can see immediately that the length of each of the sides in triangle DEF is equal to the length of the corresponding side in ABC multiplied by “a”.
3(2x - 5) = 4x + 33
6x - 15 = 4x + 33
6x - 4x = 33 + 15
2x = 48
x = 48/2
x = 24
To convert to a decimal, divide by 100.
75 / 100 = .75
