Remember
if ab=0, then assume that a and b equal 0
factor out common term
comon term in 6x^2 and 15x is 3x
3x(2x)+3x(5)=0
3x(2x+5)=0
set each to zero
3x=0
x=0
2x+5=0
2x=-5
x=-5/2
x=-5/2 and 0
Answer:
55.9548
Step-by-step explanation:
35.64 ÷ 2 = 17.82

If you divide 380 by 20, you get 19. To check this, multiply 20 x 19 to see 380. Hope this helps :D
Make a table with two columns, to find the ordered pair. This is an example.
Average rate of change of the function: 
Step-by-step explanation:
The average rate of change of a function f(x) can be calculated as:

where:
are the x-values of the interval taken into account to evaluate the rate of change of the function
are the values of the function at those points
In this problem, we have:

The function is
, so

So, the average rate of change in this interval is:
