Final answer:
More information is needed to provide the new expression after subtracting the area of the cucumber section from the initial expression 8x-2xy-36.
Step-by-step explanation:
The student asks to find the new expression for the area of the cauliflower and pepper sections if the cucumber section area is subtracted from the original expression 8x-2xy-36. The expression for the cucumber section area is not provided in the question, which means we need more information to answer this question correctly. To obtain the new expression, we would need to know the algebraic expression that represents the area of the cucumber section, then subtract it from the given expression 8x-2xy-36.
