Values of x and y will be 12 and 5 respectively.
It's given in the question,
- Three points Q, R and S are collinear.
- Coordinates of Q → (2, 0)
- Coordinates of R → (8, 3)
- Coordinates of S → (x, y)
- QR : RS = 3 : 2
Since, expression for the coordinates of a point (h, k) which divides the segment joining points 
and 
in the ratio of m : n is given by,
h = 
k = 
Since, R is a point on segment QS dividing in the ratio of 3 : 2, coordinates of R will be,
Similarly, 
Therefore, values of x and y will be 12 and 5 respectively.

X=width of a coccer pitch
2x-20=length of a soccer pitch
Area (rectangule)=length x width
We suggest this equation:
x(2x-20)=6000
2x²-20x=6000
2x²-20x-6000=0
x²-10x-3000=0
We solve this quadratic equation:
x=[10⁺₋√(100-4*1*-3000)]/2=[10⁺₋√(100+12000)]/2=
=(10⁺₋110)/2
we have two solutions:
x₁=(10-110)/2=-50, invalid solution.
x₂=(10+110)/2=60
x=60
2x-20=2(60)-20=120-20=100
Solution: the length is 100 m, and the width is 60 m.
To check:
Area=100 m*60 m=6000 m²
The twice of width is =2(60 m)=120 m,
20 m less than twice its width is: 120 m-20 m=100 m=the length.

Answer:
x=55
Step-by-step explanation:
All the sides of a triangle add up to 180
100+25=125
180-125=55
X=55 Hope this helps
