James is one-third the age of his father Steve. The sum of their ages is 68. How old is James and Steve? Plese explain in simpler words and use 'x' as the variable..
the one who answers first will get brainliest..

James + Steve = 68. = 17*3 = 51. Answer. Steve is 51 years old.

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.  

hello,

as we don't know if g(x) is continue,

answer b

f(x)=2x²-8x+1=2(x²-4x+4)+1-8=2(x-2)²-7

vertex is (2,-7) ( a minimum since coefficient of x² is > 0)
