Question 133012
The distributive property says {{{a(b+c)=ab + ac}}}.


So for {{{-5(w-8)}}},

Step 1: multiply -5 times w: {{{-5w}}}

Step 2: multiply -5 times -8: {{{40}}}

Step 3: add the two parts: {{{-5w+40}}}


Do the same thing with the other problem.  You can move the -2 to the other side of the parentheses - the commutative property says we can do that - if it makes more sense to you that way.
