Answer:

Step-by-step explanation:
Three feet make a yard, so 2 yards is 6 feet
If we divide the top (numerator) and the bottom (denominator) by 2 we get
÷
= 
Well, here's a harder one
Basically, to find a vertical asymptote, we set the denominator to 0. Like this:
x^3 - 81x = 0
Then we solve for x.
x(x^2 - 81) = 0
x(x+9)(x-9) = 0
x = 0, 9, -9
There are vertical asymptotes at x = 0, x = 9, and x = -9.
Answer:
After simplifying ur ans comes out to be option a
X = 5. Using the pythagreom theorem, a²+b²=c², to solve x we put in the numbers into the equation getting a²+12²=13². Then solve for a. a²=25, 5·5=25, a=5 which means x=5.
