Question

Evaluate 7m² + 5n² when m = 2, n = 3.
Provide your answer below:

Answer 1

To evaluate 7m² + 5n² when m = 2 and n = 3, substitute the values and simplify.

Step-by-step explanation:

To evaluate 7m² + 5n² when m = 2 and n = 3, we substitute the values into the expression:

7(2)² + 5(3)²

This simplifies to:

7(4) + 5(9)

Which further simplifies to:

28 + 45

Finally, we find that:

7m² + 5n² = 73
