Let x = 20. which expression has a value greater than 4x−10 ? 5x−100 8(x−10) 5(2x−26) 5x−30

  8(x-10)

Step-by-step explanation:

When the calculation is repetitive, I like to let a calculator or spreadsheet do it. The value of the given function is

  4·20 -10 = 70

Only the expression 8(x-10) = 8(20-10) = 80 has a larger value for x=20.

It is actually fewer keystrokes to copy the numbers into a calculator, but getting a record of results can be difficult.

goog may be able to you find that answer

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.
