= <span>(-8x - 9)(-9x2 + 7x - 9)
= 72x</span>³ - 56x² + 72x + 81x² - 63x + 81
= 72x³ + 25x² + 9x + 81
In short, Your Answer would be: Option D
Hope this helps!

The second one. 3/4.
If you want could you mark me brainliest?????
The rate of change of a function can be modeled with the following expression:

Where Δx is the change in x value, and Δk(x) is the corresponding change in k(x). We're given the two extremes of x, so we can calculate the change in x to be

To find the change in k(x), we can calculate the values of k(x) at x = -14 and x = -4 and find the difference between them:

So, the rate of change for the function from x = -14 to x = -4 is
