The stright side of the hula hoop would be 2 inches
For one it would be the mass because liquid isn’t measured in grams
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
