Jamie used the distributive property to find the product of s(t) and h(t).
his work was marked incorrect. identify jamie's mistake. what advice
would you give jamie to avoid this mistake in the future?
sct).h(t)= (3x-4)(2x-8)
= 6x2 -24x-8x - 32
= 6x2 -32% - 32

Jamie's mistake:  The last term and not . Jamie multiply the signs incorrectly.

Advice to avoid this mistake in the future: Jamie should remember that when two negative numbers are multiplied, the result is a positive number.

Step-by-step explanation:

The correct procedure is the one shown below:

You can identify that the last term is actually and not , so Jamie multiply the signs incorrectly.

To avoid that mistake in the future, Jamie must remember the mulitplication of signs:

So when two negative numbers are multiplied, the result is a positive number.

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.
