I need help with this... I marked what I think the answers are, I will attach the document in the comments. Thanks in advance!!
Btw this is not a test, its a practice and I didnt post the whole thing... only the ones that I dont understand or second guess myself on
The first one. S = 3*r^4*t Divide both sides by 3 S/3 = r^4 * t Now divide by r^4 \[\frac{ S }{ 3 r^{4} }\] You're absolutely correct!
Thank youi very much... I alsway second guess myself:\ Do you know about any of the other problems?
As for the second one it should be \(k\le-3\) \(9+3k\le0\) \(3k\le-9\) \(k\le-3\)
