I need help for this question pls

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 =

If f(x) = 2x + 8 and g(x) = x4, what is (gº)?

Are the corresponding angles congruent? explain why or why not.
