Explanation

The numbers are 2x, 3x, and 4x with an HCF of 12. So, x = 12.

Numbers are 24, 36, and 48.

Calculating LCM

LCM(24, 36, 48) = 2^4 * 3^2 = 144

Explanation

Given the equation x² - 3x - 4 = 0:

Step 1: Factor the quadratic equation

x² - 3x - 4 = (x - 4)(x + 1) = 0

Step 2: Solve for x

x - 4 = 0 or x + 1 = 0

x = 4 or x = -1

Explanation

Like terms: 2x² + 3x² = (2 + 3)x²

Result = 5x²

Explanation

3 boundaries = 3 × 4 = 12 runs

8 sixes = 8 × 6 = 48 runs

Runs from boundaries and sixes = 12 + 48 = 60

Runs by running = 110 – 60 = 50 runs

Percentage = (50 / 110) × 100 = 45.45...% = 45 5/11%
