Cd has an endpoint at (2, -1) and a midpoint at (8, 3). which measure is closest to the length of cd
stepladder [879]

Answer:

4\sqrt{13}

Step-by-step explanation:

The length of CD will be twice the distance from the midpoint to the endpoint

To calculate the length use the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = (2, - 1) and (x₂, y₂ ) = (8, 3)

d = 2 × \sqrt{(8-2)^2+(3+1)^2}

  = 2 × \sqrt{6^2+4^2}

  = 2 × \sqrt{52}

  = 2 × \sqrt{4(13)}

  = 2 × 2\sqrt{13} = 4\sqrt{13} ← exact length

Seven times a number minus the number is -48. Find the number.
irinina [24]
The answer is -8 I believe.

To put this into an equation, we get 7x-x=-48. This is equal to 6x=-48. When we divide we get -8.
