Answer:
20 tea bags
Step-by-step explanation:
if 5 is 1 gallon then you do 5x4=20
X^2+7x+10. i dont know what a middle term is but this is the answer to the equation
1 yard equals 36 inches. So 36 x 6 yards=216 inches... But you still have the half of the yard so you would divide 36 by 2 and get 18... So then you add the extra 18 inches to the 216 inches to get 234in altogether.... Hope this helped! Good luck!
Answer:
Hope this helps you to solve it
