The denarius was a unit of currency in Ancients Rome. Suppose it costs the Roman government 10 denarii per day to support 4 legionaries and 4 archers. It only cost 5 denarii per day to support 2 legionaries and 3 archers. Use a system of linear equations in two Variables.

the answer is; biodiversity resulting from few ancestors

adaptive radiation occurs when a population is subjected to a large natural environment with spatial ecological variations. the parts of the population in the different ecologies begin to adapt to their local environments. due to non-random mating across the large populations, this causes the different populations from the large population to speciate within their local environments. they, therefore, diverge to different species sharing a common ancestor.  

answer:

24pi or letter c

x^3-4x^2+3x-2/x^2+1

step-by-step explanation:

factor the numerator and denominator and cancel the common factors
