Answer:
![16\sqrt{17}](https://tex.z-dn.net/?f=16%5Csqrt%7B17%7D)
Step-by-step explanation:
The perimeter is two times width plus two times length:
![2\sqrt{17} + 2\cdot 7\sqrt{17} = 2\sqrt{17} + 14\sqrt{17} = 16\sqrt{17}](https://tex.z-dn.net/?f=2%5Csqrt%7B17%7D%20%2B%202%5Ccdot%207%5Csqrt%7B17%7D%20%3D%202%5Csqrt%7B17%7D%20%2B%2014%5Csqrt%7B17%7D%20%3D%2016%5Csqrt%7B17%7D)
There is no way to simplify further.
Answer:
This is very TRUE. They are more prone to electromagnetic interference.

Step-by-step explanation:
So, we have to find the slope of the line. We are given two points, so we can use those:
(x1,y1) = (-4,6)
(x2,y2) = (1,2)
m = (y2-y1)/(x2-x1) = (2-6)/(1--4) = (2-6)/(1+4) = -4/5
Also, we know that point-slope is of the form:
(y-y1) = m*(x-x1)
It doesn't matter which point you use, though, you can also use:
(y-y2) = m*(x-x2)
So we can plug the variables into the equation and get:
(y-2) = -4/5*(x-1)
OR
(y-6) = -4/5*(x+4)
