The solution to the given system of equation is (3, 3, 3)
<h3>Solving system of equations</h3>
Given the following system of equation expressed as:
2x-y+5z=16
X-6у +2z=-9
3x+4y- z=32
Multiply equation 2 by 2 to have:
2x-y+5z=16
2X-12у +4z=-18
Subtract
10y+z = 34 .........4
Similarly
3X-18у +6z=-27
3x+4y- z=32
Subtract
-22y+7z = -59 ........... 5
Equate 4 and 5
10y+z = 34 .........4 * 7
-22y+7z = -59 ........... 5 * 1
_______________________
70y+7z = 238
-22y+7z = -59
Subtract
92y = 297
y = 3
Recall that
10y+z = 34
10(3) + z = 34
z = 3
Since x - 6y +2z = -9
x-6(3)+2(3) = -9
x - 18 + 6 = -9
x = 3
Hence the solution to the given system of equation is (3, 3, 3)

All the factors of 28 are 1,2,4,7,14,28.
Answer:
Option (4)
Step-by-step explanation:
m(∠PZR) = 
Radius of the circle = 8
Since, length of an arc = 
Here, θ = Central angle in radians
From the given formula,
m(arc PR) = 
= 
= 
Therefore, Option (4) will be the correct option.
The equation for the perimeter of a square is P=4s (s=the length of each side)
So we can plug in the perimeter and solve for the side
48=4s
s=12 (divide both sides by 4)
The equation for the area of a square is A=s^2 or A=s*s
We can plug in the value for each side to find the area
A=12*12
A=144 units
Hope this helps!
