Final answer:
To write the phrase 'The product of 9 more than the volume, V, and 5' as a mathematical expression, we can represent the volume as V, express '9 more than the volume' as V + 9, and multiply this expression by 5.
Step-by-step explanation:
To write the phrase 'The product of 9 more than the volume, V, and 5' as a mathematical expression, we can start by representing the volume as a variable, let's say V. Then, we can translate '9 more than the volume' as V + 9. Finally, we multiply this expression by 5 to represent 'the product of 9 more than the volume, V, and 5'. The mathematical expression would be: 5 * (V + 9).
