Question

Please help 1-6?!!! I really need help on this math packet because I'm really confused and I need someone to teach me how to do it.

Answer 1

1) a
2) c
3) c . Proof: geom. means of 6 & 12 = √(6*12)=√72 = 8.458, which is between 8 & 9

4) 4*(5x-11) = 15* x ===5x=44 & x=44/5


I don't see numb 5 & 6
