Answer:
25
Step-by-step explanation:
Note x^2y + xy^2 = xy(x+y)
We know xy = 5 and x+y = 5, so
5*5=25
You need to take away 4 degrees from 92.
"Take away" means subtraction.
92 - 4
The answer is option C.
Answer:

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.
