Answer:
x - intercepts are (-7,0) and (-2,0)
A is the correct option.
Step-by-step explanation:
We have been given the equation of the parabola ![y=x^2+9x+14](https://tex.z-dn.net/?f=y%3Dx%5E2%2B9x%2B14)
For x- intercept, y = 0
![0=x^2+9x+14](https://tex.z-dn.net/?f=0%3Dx%5E2%2B9x%2B14)
We can split the middle term as 9x = 7x +2x
![x^2+7x+2x+14=0](https://tex.z-dn.net/?f=x%5E2%2B7x%2B2x%2B14%3D0)
Now take GCF
![x(x+7)+2(x+7)=0](https://tex.z-dn.net/?f=x%28x%2B7%29%2B2%28x%2B7%29%3D0)
Factored out the common term
![(x+7)(x+2)=0](https://tex.z-dn.net/?f=%28x%2B7%29%28x%2B2%29%3D0)
Apply the zero product property
![(x+7)=0,(x+2)=0](https://tex.z-dn.net/?f=%28x%2B7%29%3D0%2C%28x%2B2%29%3D0)
Solve for x
![x=-7,-2](https://tex.z-dn.net/?f=x%3D-7%2C-2)
Hence, x - intercepts are (-7,0) and (-2,0)
A is the correct option.

Step-by-step explanation:
The angle of elevation of shadow from building is 50 degrees
tan 50=height of building/length of shadow=h/75
h=75tan50=75(1.192)=89.38 feet
the height of the building is 89.38 feet
