The numbers are 5 and 2.
Reciprocals: 5- 5/10
2- 2/10
(2/10)+(5/10)= 7/10
5-2= 3
Answer: 5 and 2
<span>4x^2 - 25
= (2x)^2 - 5^2 .................using a^2 - b^2 = (a+b)(a-b)
= (2x + 5)(2x - 5)</span>
To find the average rate of change in a interval

We use the following formula:

Applying this to our interval

We have the following rate of change:

We have an average rate of change equals to 6.
Anything to the 0 power is 1
and 1 to the any power is 1
so x can be any number
