Answer:
17n+11
Step-by-step explanation:
Formula For Perimeter Of Rectangle: 2(Length) + 2(Width)
Length = 3.5n + 9
Width = 5n - 3.5
____________________________________________________
-> 2(Length) + 2(Width)
-> 2(3.5n+9) + 2(5n-3.5)
*distribute*
-> (7n+18) + (10n-7)
*distribute*
->7n+18+10n-7
->17n-11
If you subtract this problem the answer would be 13/28

Answer:
245 miles driven.
Step-by-step explanation:
A car rental company charges $10 a day and 17 cents per mile to rent their cars. 17 cents = 0.17 dollars
Let x be the number of miles and y be the number of days
total change =0.17x + 10y
Given total change is 61.65 and number of days = 2
plug in the values and find out the number of miles
61.65 = 0.17 x + 2(10)
61.65 = 0.17 x + 20
subtract 20 on both sides
41.65 = 0.17x
Divide by 0.17 on both sides
x = 245
245 miles driven.
