Question

A steel beam can be cut to different lengths for a project.

Assuming the weight of a steel beam is proportional to its length, what information would you need to know to write an equation that represents this relationship?

Answer 1

Answer:None

Explanation:

You can write a statement of proportionality without any additional information:

weight = k × length for some constant k

If you need to know the specific weight of a specific length, then you need to know the constant of proportionality (the value of k).
