Question

An equation is shown below:

km2 - c = n

Which equation is solved for m?

m = square root of c plus n over k

m = square root of c minus n over k

m = the square root of k times the quantity c minus n

m = the square root of k times the quantity c plus n

Answer 1

well, you can easily add c to the both sides and then write : km^2 = n+ m so you have to divide both sides by k: \[m^2 = \frac{ n +m}{ k }\]

Answer 2

can u say what to do next?

Answer 3

I dont know where I got the 6 from lol

Answer 4

yes,@Cosmichaotic is correct,then we should write:
\[\sqrt{m^2} = \sqrt{\frac{ m+n }{ k }}\]
