Which is equivalent to (3x + 4) – (4x – 2)?

a. 7x – 2
b. -x + 6
c. -x – 2
d. 7x + 6

-x+6

Step-by-step explanation:

Let's simplify step-by-step.

3x+4−(4x−2)

Distribute the Negative Sign:

=3x+4+−1(4x−2)

=3x+4+−1(4x)+(−1)(−2)

=3x+4+−4x+2

Combine Like Terms:

=3x+4+−4x+2

=(3x+−4x)+(4+2)

=−x+6

=−x+6

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.
