Answer:
Check attachment below
Step-by-step explanation:
To do this :
we know the graph will cross the y axis at -9 (because of the y-intercept)
And we can work out the x-intercept by making y=0 and solving for x.
This gives us 15

Answer:
Option A. ![x=10\ in](https://tex.z-dn.net/?f=x%3D10%5C%20in)
Step-by-step explanation:
we know that
The combined area of the 3 windowpanes and frame is equal to
![(3x+12)(x+12)=924\\ \\3x^{2}+36x+ 12x+144=924\\ \\ 3x^{2}+48x-780=0](https://tex.z-dn.net/?f=%283x%2B12%29%28x%2B12%29%3D924%5C%5C%20%5C%5C3x%5E%7B2%7D%2B36x%2B%2012x%2B144%3D924%5C%5C%20%5C%5C%203x%5E%7B2%7D%2B48x-780%3D0)
using a graphing tool to solve the quadratic equation
The solution is ![x=10\ in](https://tex.z-dn.net/?f=x%3D10%5C%20in)
