Factorise 5x 2 + 20x

pychu [463]

Answer:

5x^2 + 20x = 5x(x + 4)

Step-by-step explanation:

Here, we want to factorize;

5x^2 + 20x

To do this, we start by writing the common factors

The common actor that we can see which is in the form of the gcf of both is 5x

Thus, the factorization will be;

5x^2 + 20x = 5x( x + 4)

Click here What is the average rate of change for this exponential function for the interval from x=2 to x = 4? 15 10 -5 5 10 O

Triss [41]

Answer:

c. 6

Step-by-step explanation:

Given

See attachment for graph

Required

Average rate of change

This is calculated as:

$Rate = \frac{f(b) - f(a)}{b - a}$

Where

$(a,b) = (2,4)$

So, we have:

$Rate = \frac{f(4) - f(2)}{4 - 2}$

$Rate = \frac{f(4) - f(2)}{2}$

Using the attached graph, we have:

$f(2) = 4$

$f(4) = 16$

So, we have:

$Rate = \frac{16- 4}{2}$

$Rate = \frac{12}{2}$

$Rate = 6$
