Step-by-step explanation:

<u>First, write the equation as adding all the parentheses together like so:</u>

(9.7c - 1.9d) + (9.2c + 1.1f) + (8.2f - 9.3d)

<u>Remove the parentheses:</u>

9.7c - 1.9d + 9.2c + 1.1f + 8.2f - 9.3d

 3. The area of one side of the wall is:
 
 A=8 mx40 m
 A=320 m²
 
 4. Therefore, you have:
 
 1 gallon-----37.16 m²

 x=320x1/37.16
 x=8.61 gallons
 x≈9 gallons
