He expression 2(l + w) is used to calculate the perimeter of a rectangle, where l is length and w is width. if the length is fraction 2 over 3 unit and the width is fraction 1 over 3 unit, what is the perimeter of the rectangle in units? fraction 2 over 3 unit 1 unit 1fraction 2 over 3 units 2 units

I'm confused on this could anyone me and show me what i need to do to solve it.

Which inequality is equivalent to -3x < -12? x < 4 , x < -4 , x > 4, x > -4
