Question

What’s equivalent to z+(z+6)

Answer 1

Actually it is 2z+6z

Z times z and z times 6

Answer 2

2z + 6

Explanation:

Since nothing can be done with the brackets we can take those out. We would end up with

z + z + 6

As you can see we have two z's and we can add those together. This would give us our answer:

2z + 6
