I think this should be the answer!!
Answer: 
Step-by-step explanation:
Given
Function is 
Zeroes of the function are

Using completing the square method


The coefficient is a number before a variable.
Here, the coefficient is 9.
The like terms are any terms that have the same variable.
Here, 9k and -k are like terms, and 7 and 4 are like terms as well.
Combine like terms:
8k+3
The constants are: 7 and 4 (Constants are numbers in an expression or equation)
After combining like terms, the constant became
3

here's the solution,
we know :

So,

so.. let the perpendicular be 12x and hypotenuse be 13x
now,
by applying pythagoras theorem,
where,
- b = base
- h = hypotenuse
- p = perpendicular
So,
so,
hope it helps !!
