A chemical compound has a freezing point of -5°C and a boiling point of 97°C. What is the difference between the freezing point and the boiling point of the chemical compound?

Two lines that do not intersect are skew. always sometimes or never

Hi my sisters and brothers can tell me the answer because i don’t understand the question

The first few steps in solving the quadratic equation 9x2 + 49x = 22 ? 5x by completing the square are shown. 9x2 + 49x = 22 ? 5x 9x2 + 54x = 22 9(x2 + 6x) = 22 which is the best step to do next to solve the equation by completing the square? 9(x2 + 6x + 3) = 25 9(x2 + 6x + 3) = 49 9(x2 + 6x + 9) = 31 9(x2 + 6x + 9) = 103
