Answer:
The correct option is 3.
Step-by-step explanation:
The given expression is
Two or more terms are called like terms if they have the same variables and powers.
In the given expression 5x and 4x are like terms.
On combining like terms we get
The simplified form of given expression is 9x-6y. Therefore the correct option is 3.

Step-by-step explanation:
<u>Increasing and Decreasing Intervals of Functions</u>
Given f(x) as a real function and f'(x) its first derivative.
If f'(a)>0 the function is increasing in x=a
If f'(a)<0 the function is decreasing in x=a
If f'(a)=0 the function has a critical point in x=a
As we can see, the critical points may define open intervals where the function has different behaviors.
We have
Computing the first derivative:
We find the critical points equating f'(x) to zero
Simplifying by -6
We get the critical points
They define the following intervals
Thus A=3 and B=6
