152
Step-by-step explanation:
45 seconds = 45/60 minutes = 3/4 minutes . Number of copies = 4*32 + (3/4)*32 = 128 + 24 = 152
a - b is 9
Step-by-step explanation:
- Step 1: Given a² + b² = 1305, a × b = 648. Find a - b using the identity for (a - b)²
⇒ (a - b)² = a² + b² - 2ab
⇒ (a - b)² = 1305 - 2 × 648 = 1305 - 1296 = 9
⇒ (a - b) = 9
