that is the ordered pair of the solution:)
= (5a²)³ - 4³
you can apply the cubic factorisation rule
(a³ - b³) = (a - b)(a² - ab + b²)
= [5a² - 4][ (5a²)² - 20a² + 16]
= [5a² - 4][25a⁴ - 20a² +16]
I think this is it.
hope it helps.

Answer:
4.08 inches.
Step-by-step explanation:
A cube has six sides, and each of the sides has area of , where is the length of the edge of the cube.
Thus the total surface area of the cube is
Now we are told that this surface area is 100 square inches, therefore , and now we can solve for :
A. Subtract two from both sides because you need the value of y to be by itself so that you can divide it later on
