Answer 13

Does your question say you can round to the nearest tenth or whole number?
You could either put 7, 6.9, or 6.93

Answer 14

its what is the value of the expression...

Then If I was you, I would put the answer to it's hundredths, which is: 6.93

D. 3

Answer 18

what are the values of a and b?

Answer 19

Answer 22

If I was you I would just put B.

Answer 23

ok

Answer 24

Are those really the only choices? Because if it is, the only right answer would be D. 3.. Because radical signs, moreover square root only gives positive answers

Answer 25

Either B or D are the answer.
