B. is the answer because he can just refill the 1 gallon jug to eventually measure out 3 gallons!
Answer:
30 in.
Step-by-step explanation:
You have to add the current length of the board with the length that was cut off.
18 + 12 = 30
y= -4x² - 16x - 14
Take the coefficient of x² as the common factor
y = - 4(x² + 4x + 7/2)
Add (b/2)² to complete the square
y = - 4( x² + 4x + 2² - 2² + 7/2)
Complete the square
y = -4( (x + 2)² - 1/2)
Remove the bracket
y = -4(x + 2)² + 2
Answer: y = -4(x + 2)² + 2
6 feet is longer because 6 feet = 72 inchs
and because 70 feet = 5.83333
