Simplify each only using positive exponents:
2x^-3 • 4x^2
2x^4 • 4x^-3
2x^3y^-3 • 2x

Answer! if you don’t mind, can you explain

Factor the polynomial by its greatest common monomial factor.

4. (10.03 mc) the equation of line cd is y = −2x − 2. write an equation of a line parallel to line cd in slope-intercept form that contains point (4, 5). (4 points) y = −2x + 13 y = negative 1 over 2 x + 7 y = negative 1 over 2 x + 3 − 2x − 3
