-4 is the x intercept.as in the values on the x-axis
Answer:
the solutions of x^2=16x-28 are
2) 2 and 14
The length will be 17.
Perimeter equation is L+L+W+W= Perimeter
9+9+W+W=Perimeter
I took 18 and subtracted it from 52 and got 34.
Since we are calculating one side length I divided by 2 which got me to 17.
You have to multiply by 16's and then divide the two numbers
60 minutes. Take how far it is above ground (20 m) and add it to the absolute value of how far it is below ground (340 m) to get 360 meters, which you divide by the rate of descent (6 m/min) to get 60 minutes.
