    first use the distributive property we just discussed, what do you get?

    just do this part first: simplify -3(d - 3) and tell me what you get

    remember the distributive property? a(b+c)=ab+ac use that on -3(d-3) and tell me what you get.

    Multiply D by -3 and multiply -3 by -3. So d*-3= ? and -3*-3=?

    see how the -3 gets "distributed"?

    So, it would be -3d?

    the first term is -3d but what about (-3)(-3)?

    you believe that -3d+9=6d no remember to only combine "like terms" I will tell you that -3d+9 cannot be simplified As to your second question, we haven't even answered the first! Remember, one step at a time!

    -3d+9d=6d because they both have a "d" in them but -3d+9 has no "d" next to the 9, so it cannot be simplified now let's remember our original problem: -3(d - 3) + 5d we have established that -3(d-3)=-3d+9 so we now have -3d+9+5d can you simplify that?

    yes, nice job. Please focus on the part you had trouble with -3(d-3)=-3d+9 and see how it follows the distributive property, which is a(b+c)=ab+ac
