Answer:
8n-1
Step-by-step explanation:
it would be 8n-1 because you combine like terms
The platform is square. Let the length of one side be x.
Then the perimeter is P = 6x - 6 = 4x
Then 2x = 6 and x = 3. The side length is 3.
Check: P = 4(3) = 12
P = 6(3)-6 = 12
These agree.
180 * 365 = 65700 litres/year
65700 / 1000 = 65.7 m^3/year
0.9122 * 65.7 = £59.932 for water used
28.20 + 59.93 = £88.13 for water meter annually
£88.13 < £107 so yes, he should have a water meter.
