Question

Help me with number 2,3,4,5 please

Answer 1

2. They are equivalent, because they are like terms.

3. They are equivalent because when you add b 5 times, you are multiplying b by 5.

4. They are equivalent because when you multiply 4 by x you get 4x, then multiply 4x by x which gives you 4x² Since you multiplying x by x you square x.

5. They are not equivalent because c is being added 3 times which would give you 3c then you are adding it to 7. therefore it is not equivalent
