distribute in   4(7x - 1)   what do you get?

anonymous · Answer

um, idk.. cant think of it

anonymous · Answer

24x

jigglypuff314 · Answer

use the distributive property
      a(b-c) = ab - ac
so 4(7x-1) = ?

anonymous · Answer

4*7 - 4*1
28  - 4
    24

close! :)
remember that you can't add or subtract terms that have different amounts of x
so  28x - 4   can't be subtracted
it would just be left like that
but now do you see the difference in what "Max" did wrong? :)
