Answer:
![x^2 + 14x + 40](https://tex.z-dn.net/?f=x%5E2%20%2B%2014x%20%2B%2040)
Step-by-step explanation:
Here we gonna use the identity -
![(x+a)(x+b) = x^2+(a+b)x + ab](https://tex.z-dn.net/?f=%28x%2Ba%29%28x%2Bb%29%20%3D%20x%5E2%2B%28a%2Bb%29x%20%2B%20ab)
So using the identity here,
![(x+4)(x+10) \\=> x^2 +(4+10)x+4*10\\=>x^2+14x+40](https://tex.z-dn.net/?f=%28x%2B4%29%28x%2B10%29%20%5C%5C%3D%3E%20x%5E2%20%2B%284%2B10%29x%2B4%2A10%5C%5C%3D%3Ex%5E2%2B14x%2B40)
Answer: The answer is C.
Step-by-step explanation: This is because when you solve you get y=1/10x+6.5 this graph runs through the point (5,7) and is perpendicular to y=-10x+1. In order for two equations to be perpendicular their slopes will be the opposite.
