Simplify 2 x2 - y for x = 3 and y = -2.

2

Step-by-step explanation:

Substitute {x=3

{y=2

~~into 2x2-y

2x2-2

4-2

so the answer is 2.

answer: no

step-by-step explanation:

you are only given the cost not the amount of pounds.

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.
