Does your question say you can round to the nearest tenth or whole number? You could either put 7, 6.9, or 6.93
anonymous
  • anonymous
its what is the value of the expression...
anonymous
  • anonymous
Then If I was you, I would put the answer to it's hundredths, which is: 6.93

\[\sqrt{a^2-b+19-4^2}\]
anonymous
  • anonymous
but the answers are A. -6 B. -7 C. -8 D. 3
darkprince14
  • darkprince14
what are the values of a and b?
anonymous
  • anonymous
Answer was b. -7 (Rounded to whole number)
anonymous
  • anonymous
A=7 and B=4
anonymous
  • anonymous
they are both positive
anonymous
  • anonymous
If I was you I would just put B.
anonymous
  • anonymous
ok
darkprince14
  • darkprince14
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
anonymous
  • anonymous
Either B or D are the answer.
anonymous
  • anonymous
honestly im not sure. i will just put it as -7 and let you both know after submitting the assignment
darkprince14
  • darkprince14
I want to apologize for pointing it out but it won't make sense if the answer is negative...
anonymous
  • anonymous
exactly
anonymous
  • anonymous
Pick D.
anonymous
  • anonymous
ok
anonymous
  • anonymous
Well I'm off, I hope you get it correct!
anonymous
  • anonymous

darkprince14
  • darkprince14
Do you really have to pick one from the choices?
anonymous
  • anonymous
yes
darkprince14
  • darkprince14
oh... I remember when I quarreled with my math teacher because the choices she gave were wrong... I ended up getting bonus points XD.. Anyway, it's your work so good luck!!!
