2/9 = 14/n
14÷2/9 = 14/n÷14
63 = n
So, n=63

The value of variable x of provided quadratic function at h(x) = 18 are 6.56 and -0.13. These points explain solution of the equation.
<h3>What is quadratic formula?</h3>
Quadratic formula is the formula which is used to find the roots of a quadratic equation.The standard form of the quadratic equation is,
ax²+bx+c=0
For the above equation, the quadratic formula can be given as,
The equation of variable x is given as,
h(x) = 7x²-45x + 12,
The value of h(x) = 18 has to be found out. Put 18 on the place of h(x) in the above equation.
18 = 7x²-45x + 12
0= 7x²-45x + 12-18
0=7x²-45x -6
Find the roots of the equation using the quadratic formula:
Thus, the value of variable x of provided quadratic function at h(x) = 18 are 6.56 and -0.13. These points explain the solution of the equation.

Answer: hypotenuse=16
Step-by-step explanation:
First, you need to know the concept of a special triangle 30-60-90. The corresponding ratio of each side is 1-√3-2. Basically means, the shortest side is 1, the other longer leg is √3, the hypotenuse is 2. You can also refer to the attachment below
For this question, given the shortest side is 8, and asked to find the hypotenuse.
Short side:hypotenuse=1:2
8:hypotenuse=1:2
hypotenuse=16
Hope this helps!! :)
