Can anybody help me as soon as possible. Model with mathematics. The weight of a pen manufactured at the PEN factory is 8g. The actual weight can vary as much as 2g. Write and solve an inequality to represent all acceptable weights for a pen at this factory. *25 POINTS*

Write an equation of a line in slope intercept form that is perpendicular to the line 2x -3y = 12 and passes through the point (2, 6).

Which approach to the theory-and-research cycle does the following sequence reflect: (1) specific observations suggest generalizations, (2) generalizations produce a tentative theory, (3) the theory is tested through the formation of hypotheses, and (4) hypotheses may provide suggestions for additional observations?

Could somebody me with this radical simplification?
