The expression "4Q - 1" represents a mathematical expression involving a variable \( Q \). If you have a specific value for \( Q \), you would substitute that value into the expression and calculate the result. For example:
- If \( Q = 2 \):
\( 4Q - 1 = 4(2) - 1 = 8 - 1 = 7 \)
If you have a specific value for \( Q \) in mind, let me know, and I can help with the calculation!
