I assume it is 100 meters, not 100100 meters.
Length (L)=width(w)+4
Perimeter: 2L+2W>100
Plug L=W+4 into the equation 2L+2W>100:
2(W+4)+2W>100
2W+8+2W>100
4W+8>100
4W>92
W>23
the width needs to be at least 23 meters
For this case we have the following system of equations:
5x + 3y = 17
-8x - 3y = 9
We can rewrite the system like:
Ax = b
Where,
A = [5 3; -8 -3]
b = [17; 9]
x = [x; y]
The determinant of matrix A is given by:
lAl = ((5) * (- 3)) - ((3) * (- 8))
lAl = (-15) - (-24)
lAl = -15 + 24
lAl = 9
Answer:
The determinant for solving this linear system is:
lAl = 9
Equation for a circle
r^2 = (x - h)^2 + (y - k)^2
where r = sqrt[ (-2 - (-10))^2 + (-5 - (-20))^2]
sqrt[ (8)^2 + (15)^2 ]
sqrt[ 64 + 225 ]
= sqrt[289] = 17
equation for a circle
17^2 = (x - (-2))^2 + (y - (-5))^2
17^2 = (x + 2)^2 + (y + 5)^2
