617. a³ - b³ , a² - b² , a² + ab + b² and x are in a proportion. The value of x is ___?

Check answer and explanation

Answer: a + b

Explanation Given the proportion: a³ - b³ : a² - b² :: a² + ab + b² : x We know a³ - b³ = (a - b)(a² + ab + b²) and a² - b² = (a - b)(a + b) So, the proportion becomes: (a - b)(a² + ab + b²) : (a - b)(a + b) :: a² + ab + b² : x Canceling (a - b): (a² + ab + b²) : (a + b) :: a² + ab + b² : x This implies x = a + b.

618. What is the value of x if 16 : 24 :: x : 72?

Check answer and explanation

Answer: 48

Explanation The given ratio is 16:24, which can be simplified as 2:3 (by dividing both numbers by 8). To maintain the same ratio, we need to find the number that will maintain the 2:3 ratio with 72. Let's multiply 72 by 2/3: (2/3) × 72 = 48 So, the correct answer is: 48 The ratio 16:24 is equivalent to 2:3, and similarly, the ratio ? : 72 is equivalent to 2:3, which leads to the answer 48 .
