Simplify this expression: 4p  + 9 + (–7p) + 2              a.  3p  + 11    b.  11p  + 11    c.  –3p  + 11    d.  3p  + 7

4p - 7p + 9 + 2
= -3p + 11
=C

A. p = 2(l + w)p/2 - l = ww = p/2 - l b. while isolating the variable w in the equation, i first divided both sides by 2 and then i subtracted l from both sides. i hope this .
