Here,

  • x+y=1212••••••\bold{equation~I  } 
  • x-y=518••••••\bold{equation~II   } 

ADDITIONALL,both two equation.

we get that,

  • x+y+x-y=1212+518
  • 2x=1730
  • x=865

so,

  • x-y=518
  • 865-y=518
  • y=860-518
  • y=347

The length width and height of a rectangular solid are 8,4,1 respectively what is the length of the longest line segment whose e
LUCKY_DIMON [66]

Answer:

9 units

Step-by-step explanation:

Given

Length = 8

Width = 4

Height = 1

Required

Determine the length of the longest segment

To do this, we use:

Longest = \sqrt{Length^2 + Width^2 + Height^2}

So, we have:

Longest = \sqrt{8^2 + 4^2 + 1^2}

Longest = \sqrt{64 + 16 + 1}

Longest = \sqrt{81}

Take positive square root

Longest = 9

<em>Hence, the length of the longest segment is 9 units</em>
