Answer:

Step-by-step explanation:
So we have the equation:

And we want to solve for R.
First, let's multiply both sides by J to remove the fraction on the right. So:

Simplify the right:

We can rewrite our equation as:

So, to isolate the R variable, divide both sides by I²t:

The right side cancels, so:

And we are done!
Answer:

Step-by-step explanation:
Use the Pythagorean Theorem

and
are either opposite or adjacent
is the hypotenuse.
1. Look for the right angle. (the little box). The right angle "points" to the hypotenuse. In this case, the hypotenuse is 25.
2. Because we know the hypotenuse is 25. We know that 24 is our adjacent. Meaning our missing side is the opposite.
3. Plug in the numbers. 
4. Solve:

Step-by-step explanation:
Each side after the cut-out is (s-2c) where s is the original side length and c is the size of the cut so:
V=hlw, h=x and l and w are both (x-8)
V=x(x-8)(x-8)
V=x(x^2-16x+64)
V=x^3-16x^2+64x
