Answer:

The correct option is D.

Step-by-step explanation:

The given expression is

(4-\sqrt{7})(4+\sqrt{7})

Difference of two squares property:

a^2-b^2=(a+b)(a-b)

Using the above property, the given expression can be written as

(4)^2-(\sqrt{7})^2

Applying square we get

16-7

9

Therefore the correct option is D.

Use the table of values below to select the correct statement.
quester [9]

Answer:

Linear function with rate of change/growth = 2.5, which agrees with the fourth statement listed in the answers options.

Step-by-step explanation:

Notice that both columns of reported x and y values are increasing.

Then examine how the given x-values  increase:

-2, 2, 6, 10, 14  (in steps of 4 units)

and how their corresponding y-values increase:

-2, 8, 18, 28, 38  (in steps of 10 units)

therefore, if we do the rate of change for any pair (x_1,y_1) and (x_2,y_2), we get the following constant rate of change:

\frac{y_2-y_1}{x_2-x_1} = \frac{10}{4} =2.5

Given that this relationship is valid for any pair of (x,y) values. we conclude that the rate of increase is constant, and therefore we are in the presence of a linear function, whose rate of change is 2.5
