Question

Simplify this expression;
3(2x+7)

Answer 1

You should try the distributive property of multiplication:

3(2x+7)

=

3 x 2x = 6x

3 x 7 = 21

Therefore:

6x + 21

Answer 2

6x+21 (Maybe)

Are you doing the buddy method, how is your teacher wanting to do this, When you respond I might have the correct answer

(buddy method) Multiply the 2x and 7 by the 3 giving you 6x+21 and then that's it you cant do anything else but I don't know if that's how you're teacher wants it done.
