Answer:

8

Step-by-step explanation:

The numbers are 6 and 2x, then:

  • 1/6 + 1/(2x) = 7/24
  • 1/3 + 1/x = 7/12
  • (x+3)/(3x) = 7/12
  • 12(x+3) = 7*3x
  • 12x + 36 = 21x
  • 21x - 12x = 36
  • 9x = 36
  • x = 4

The other number is 2*4 = 8

Answer:

  -864

Step-by-step explanation:

The determinant of a matrix product is the product of the determinants. The determinant of a transpose is the same as the determinant of the original. Hence ...

  |AB^5C^T|=(4)(-2)^5(\frac{1}{4})=-32

The multiplication of an n×n matrix by a scalar 'a' multiplies its determinant by a^n, so the desired determinant is ...

  |3AB^5C^T|=3^3(-32) = \boxed{-864}
