Final answer:
The simplified form of the expression 7.5 + 5f + 16.2 + 2f is 23.7 + 7f after combining like terms, which are the constants and the variable terms.
Step-by-step explanation:
The question asks for the simplification of the expression 7.5 + 5f + 16.2 + 2f. To simplify this expression, you combine like terms. The like terms in this case are the constants (7.5 and 16.2) and the variable terms (5f and 2f).
First, add the constants:
7.5 + 16.2 = 23.7
Then, add the variable terms:
5f + 2f = 7f
Now, you can write the simplified expression:
23.7 + 7f
No further simplification is possible unless a value for f is given.
