Answer: 7 times 4
Step-by-step explanation:
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
Answer:
2.4m+1.8b−32.6
Step-by-step explanation:
Group like terms together
1. 2.4 m + \left( - 125 + 92.4 \right) + 1.8 b2.4m+(−125+92.4)+1.8b
2
. Add or subtract the numbers
2.4 m- 32.6 + 1.8 b2.4m−32.6+1.8b
3
. Rearrange the expression
2.4 m + 1.8 b- 32.62.4m+1.8b−32.6
