Use the expression 9(7 + 2x) to answer the following: part a: describe the two factors in this expression. (4 points) part b: how many terms are in each factor of this expression? (4 points) part c: what is the coefficient of the variable term? (2 points)

Part A: Describe the two factors in this expression. (4 points) The factors are (1) the constant coefficient 9 and (2) the binomial (7+2x).

Part B: How many terms are in each factor of this expression? (4 points) The first factor (multiplicand), 9, has one term. The second factor (multiplicand), (7+2x), has two terms (and is thus called a binomial).

Part C: What is the coefficient of the variable term? (2 points) The only such coefficient is 2.

Part A:

One of the factors is 2 and x are factors of 2x, and the second factor is 9 and (7 + 2x) because they are factors of 9(7 + 2x).

Part B:

There are 2 terms in the expression 9(7 + 2x).

Part C:

The coefficient of this problem is 2

Step-by-step explanation:

I did this test.

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.
