A square and a rectangle have the same area. The length of the rectangle is twelve more than twice times the side of the square. The width of the rectangle is eight less than the side of the square. Let x be the length of the side of the square. Using the information above, what is the value of x?

Step-by-step explanation:

Given

Shapes: Square and Rectangle

Square:

Rectangle:

Required

Find x

First, we calculate the area of the square.

Next, we calculate the area of the rectangle

Since both areas are equal, we have:

Equate to 0

Expand:

But x can't be negative.

Hence:

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.  

probably the last option
