Can someone give me an example of a direct variation that involves social studies? if not, business is alright too, thanks!​

Find the roots of the equation below. x^2 - 6 + 9 = 0

Follow these steps using the algebra tiles to solve the equation −5x + (−2) = −2x + 4. 1. add 5 positive x-tiles to both sides and create zero pairs. 2. add 4 negative unit tiles to both sides and create zero pairs. 3. divide the unit tiles evenly among the x-tiles. x =

Which of these triangle pairs can be mapped to each other using two reflections?
