Final answer:
The question pertains to forming and evaluating an expression from a tape diagram, but the necessary details to do so are missing. A general approach would involve writing a statement, forming an expression, simplifying by combining like terms, and checking the result to ensure it is reasonable.
Step-by-step explanation:
The question seems to be asking how to form a mathematical statement and expression from a tape diagram and how to evaluate the expression. However, the provided information is incomplete, so a specific tape diagram cannot be addressed here. Nonetheless, I can illustrate how to approach such a problem with a hypothetical scenario and a general process.
Suppose we have a tape diagram with sections marked 14, 46, and 14, and a variable 'a' representing an unknown section. The statement could describe the relationships indicated in the diagram, such as 'the total length of the tape is the sum of each section.' An expression that represents this could be: 14 + 46 + 14 + a. The value of the expression would be determined by substituting a known value for the variable 'a' and calculating the result.
Due to the lack of specific information on 'a' or the diagram's details, I cannot provide the actual value of the expression.
To eliminate terms in a more involved algebraic expression from a tape diagram, you would combine like terms and simplify the expression as much as possible. Afterwards, always check to ensure the answer is reasonable given the context of the problem.
