Answer:

  • 47047

Explanation:

We know that:

  • Given expression: 5x − 6y + 20z4yz
  • x = 5
  • y = 3
  • z = 14

Solution:

  • 5x − 6y + 20z4yz
  • => 5(5) - 6(3) + (20)(14)(4)(3)(14)
  • => 25 - 18 + (20)(14)(4)(42)
  • => 7 + (280)(4)(42)
  • => 7 + (280)(168)
  • => 7 + 47040
  • => 47047

Hence, the solution of this problem is 47,047.

Answer:

47,047

Explanation:

x = 5, y = 3, and z = 14 so

5*5 - 6*3 + 20*14*4*3*14

= 25 - 18 + 20*12*14²

= 7 + 20*12*196

= 7 + 240*196

= 47,047
