How do i write 0.225 as a fraction in simplest form

Which of the following describes the symmetry of the graph of y = x3?

Write the point-slope form of the line passing through (2, -12) and parallel to y=3x.

Hell . what are the solutions to `10x^2 - 38x - 8 = 0`? is this when i find the factors and use the numbers within the factors to determine the zeros? i hope that made sense lol
