Question

1 question? algebra?! Am I correct?

Answer 1

Solve 7v^2 + 49 = 105, where v is a real number
Round your answer to the nearest hundredth
If there is more than one solution, separate them with commas

Answer 3

Umm
I don't believe that is correct

Answer 4

Answer 5

First you have to put it all on the same side so you get
\[7v^2-56=0\]

Answer 6

then I would put it into quadratic formula\[x=\frac{ -0\pm \sqrt{0^2-4(7)(-56)} }{ 2(7) }\]
