The diagram represents the area of a rectangle as 9x2 + 24x + 16 square units. A 2-column table with 2 rows. The labels for the columns and rows are question mark. First column entries are 9 x squared, 12 x. Second column entries are 12 x, 16. What are the length and width of the rectangle in terms of x? both: 3x + 4 units both: 3x + 8 units width: 3x + 4 units; length: 6x + 12 units width: 3x + 8 units; length: 6x + 8 units

3x + 4 units

Step-by-step explanation:

we know that

A trinomial is a perfect square trinomial if it can be factored into a binomial multiplied to itself

so

both  and  are perfect squares

hence

therefore

the answer is  

both:  3x + 4 units

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.
