Are 5n + 9 + n and 3(2n+9) equivalent expressions

No

Step-by-step explanation: If you simplify the first expression, you get 6n + 9, and if you simplify the second expression, you get 6n + 27. So they are NOT equivalent.

No, 5n+9+n is not equivalent to 3(2n+9)

Step-by-step explanation:

5n+9+n

and

3(2n+9)

5n+9+n

Add the common terms

5n+n+9=6n+9

5n+9+n=6n+9

Then,

3(2n+9)

Open the bracket

We have,

6n+27

3(2n+9)=6n+27

Therefore,

5n+9+n is not Equivalent to 3(2n+9)
