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
Dew point.
the temperature to which a parcel of air must be cooled to reach it saturation point.
Pretty sure the answer to this question is neurons or nerve cells.
1) biological evolution
if the genes changes keeps increasing means its going through evolution
I’m pretty sure it’s B. Relative saying
