Answer: x = 995
Step-by-step explanation:
In this equation our log doesn't have a base so it is given the default base of 10. This makes our equation really.

Now we put every equation as the exponent of our base 10 looks like this:

Now we cancel out the log base 10 and the 10. We are left with:
(x+3) + (2) = 10^3
Lastly solve for x
x + 5 = 1000
x = 995
Well for a cube V= a3 so you would do a x a x a and since it is a cube all sides are equal so you would multiply 13 x 13 x 13 which equals 2,197
Answer:
x=21
Step-by-step explanation:
Set the two similar sides in a fraction to be compared and set them equal to another set of similar sides whose values are already known. Solve from there. See work for more.
