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)=-x^2+6x-1 and g(x)=3x^2-4x-1,find(f+g)(x)

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