In this question it is given that

And we have to find the value of the given limit

Using properties of limit, first we separate the two functions, that is

Substituting the values of the given limit,

Answer:
=7x
Step-by-step explanation:
We can use the slope-intercept form of the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.
From the graph, we see the line crosses the y-axis at y = 15. That means the y-intercept is 15, and we have so far y = mx + 15.
Now we need the slope. On the graph we see that for every 3 units up in y, there is 1 unit to the right in x. The slope is 3/1 = 3. m = 3. Now we add the slope to the equation.
y = 3x + 15
Answer: y = 3x + 15
Well, you can do
area=legnth times widht
perimiter=2(legnth+width)
then you just subsitute x for legnth and y for width then solve
area=xy
perimiter=2(x+y)
then graph and find the intersection to find the solution
