If I understood the question right I believe the answer should be

㏒₉(0.877) = -0.05973

hope this helped

Alright, this question is a bit confusing, but hopefully this will help:

Remember that Log(a) B = C is actually a^C = B. (Just imagine "a" as the little number that is first written after "Log.")

So here, I think Log(9) 0.877 = "x." And you want the value "x."

9^x = 0.877, which is all I've got, cause I don't really know what this "change of base rule" is. But I hope I helped.

The length of a rectangle is 3 times longer than its width. If the area of the rectangle is 24 square inches, then what is the p

Answer: The answer is 16√2 cm.

Step-by-step explanation: Given that there is a rectangle with length 3 times than its width. We are to find the perimeter of the rectangle.

Let 'w' represents the width of the rectangle.

Then, its length will be 3w.

Also, area of the rectangle = 24 square inches.

Therefore,

$3w\times w=24\\\\\Rightarrow 3w^2=24\\\\\Rightarrow w^2=8\\\\\Rightarrow w=2\sqrt 2.$
