g(x)=3xsquared-21x
=3(-2squared)-21(-2)
=3(4)+42
=12+42

4.9 convert it fraction = 49/10
To solve this you would divide until you can’t. I recommend staying in whole numbers:) I always divide by twos because I think it’s more efficient! 4 divided by 2 is 2 and 30 divided by 2 is 15 sooo (2 hours to 15) hope this helped!
