Solve this equation: - 1/5b - 2/5 = -2

How do i solve using pythagorean theorem?

What is the standard form of -5x^2+2x^4-11+x^3+3x

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 =
