Answer:
4n=y
Step-by-step explanation:
because 4 is the number of characters they use and n is the number of spaces or characters it takes
y=3^n
I just took the test and that was the right answer.
369 miles
82 miles =2 gallons
41 miles = 1 gallon
369 miles = 9 gallons
=(3x2 + 2x + 4) - (x2 + 2x + 1)
Combine like terms
=(3x2-x2)+(2x-2x)+(4-1)
=2x2+0+3
The 2x terms cancel each other to 0
=2x2+3
C) 2x2+3 is the answer.
Hope this helps!
