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.

The volume of the prism = 14 ft³
Solution:
Number of cubes in the prism = 1750
Edge length of each cube (a) =
ft
<u>To find the volume of each cube:</u>
Volume of each cube = a³

Volume of each cube 
<u>To find the volume of the prism:</u>
Volume of the prism = Volume of each cube × Number of cubes

= 14 ft³
The volume of the prism = 14 ft³
Answer:
10
Step-by-step explanation:
5 - 5 = 0 You would want to subtract five from zero giving you -5.
First, write it as an equation
2.50+3x=5.05
Next, subtract 2.50 from both sides
2.50-2.50+3x=5.05-2.50
3x=2.55
Divide 3 on both sides
3x/3=2.55/3
x=0.85
