Step-by-step explanation:

I am giving you help but not the answer, that is the best way to learn it. My work basically gives the answer and I hope that you can figure it out!! Sorry if you don't like this way.

Step-by-step explanation:

3(3)+2(3+1)-4=16+3(3)-3

13=22

False, 13 does not equal 22

So v=3 is not the right answer

3(6)+2(6+1)-4=16+3(6)-6

28=28

True, 28 equals 28

So v=6 is correct

Now you know the work, see which statements are true. :)
