There can only be two definite x-intercepts, so your goal it to find 2 numbers of x that, when plugged into the equation, give you the answer of 0. 1 is the first x-intercept(4-24+20 equals 0). The second one is 5 (100-120+20 equals 0). So the average is 3, so the axis of symmetry is 3 since 5+1=6, and 6/2=3
Honestly, there is an easier way to find the axis of symmetry. the equation would be -b/2a, where as b is the coefficient in the second part of the equation, while a is the first coefficient in the equation. -(-24) is 24, and 4*2=8, so 24/8=3
I hope I actually answered this the way you wanted. You asked for an equation, but I just answered the axis of symmetry with very simple equation initially and another equation

Answer:
31.13
Step-by-step explanation:
If you look carefully, you will find a semicircle and a triangle.
The total area is =
![\frac{\pi r^{2}}{2} + \frac{1}{2} \times base \times height\\](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20r%5E%7B2%7D%7D%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%20base%20%5Ctimes%20height%5C%5C)
- r = 4 - 0 = 4
- base = |-4-0 | = 4
- height = 14 - 9 = 5
So if we put the values:
![\frac{\pi \times 4^{2}}{2} + \frac{1}{2} \times 4 \times 3\\= 31.13](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cpi%20%5Ctimes%204%5E%7B2%7D%7D%7B2%7D%20%2B%20%5Cfrac%7B1%7D%7B2%7D%20%5Ctimes%204%20%5Ctimes%203%5C%5C%3D%2031.13)
