Answer:
x^2 + x-72=0
Step-by-step explanation:
x(x+1) =72
Distribute
x^2 +x = 72
Subtract 72 from each side
x^2 +x - 72 = 0
Now this is the equation we can factor

Answer:</h2><h2>
The correct option is d. (i) and (ii)</h2>
Step-by-step explanation:
The total miles covered per day = 45
No of commuting days in a week = 5
Total miles in a week = 45 * 5 = 225
The total amount spent on gasoline = $ 38
Cost of gasoline per gallon = $ 2.48
The number of gallons consumed per week = 
= 15.32 gallons of gasoline per week.
This confirms (ii) statement
The amount spend on gasoline per mile = 
= $0.17
This confirms (i) statement
The number of miles per gallon of gasoline = 
= 14.68 miles
The statement (iii) is false.

I see 2 answers here. Company C and D at 8 months... (Companies A and B at 5 months)
Explanation:
I took the Maximum and subtracted it by the Minimum.
Ex. Company D: 27 (Max) - 19 (Min) = 8 months
32/6 - 4 5/7
32/6 - 20/7
52/21 = 2 10/21 or 2.47
