Terms: 6m , -2n, 7
Coefficients: 6, -2
Constants: 7
Step-by-step explanation:
terms are the parts of the expression so 6m, -2n and 7

Let n be the amount of time it takes william to cut the lawn. Then Shelly takes
n-2 hours. So:
1/n+1/n-2=1/3
3(n-2)+3n=n²-2n
6n-6=n²-2n
n²-8n+6=0
Using the quadratic formula, we get a positive value of 7.1623 hrs as the amount of time william takes working alone, and 5.1623 as the amount of time Shelly takes working alone
