When fireworks display made of copper is burned, it lets out light with wavelengths, v v, that satisfy the relationship | v − 455 | < 23 |v-455|<23. Write this inequality without absolute values, find the range of possible values for v v, and then using the preceding list of wavelengths, determine the color of that copper fireworks display.

What statement is true? 2x^2-9x+2=-1
