Final answer:
Expressions A) 68 B) 104 C) 96 D) 88 are already simplified and cannot be further expressed.
Step-by-step explanation:
To simplify and express each expression, you need to clarify what you mean by 'expression.' An expression is a combination of numbers, variables, and operations. It can be as simple as a single number or as complex as a mathematical formula.
Without more context, it is not possible to simplify the expressions A) 68, B) 104, C) 96, D) 88. These are already simplified and cannot be further expressed.
