The rate mainly effects the size of the crystals in the rock forming
First of all just to point out that this isn't a biology question :)
Ok so to solve this you have to expand to spare first
8k(4k^2-12k+9)
Then multiply the 8k
32k^3-96k^2+72k is the answer
It was closely linked to the natural world
Fungi I hope this helps haha
