Answer 1

Answer: not 20. It’s the 20 with the symbol in front of it.

Explanation:

I’m just right

Answer 2

Length of VW = 4.47 units

Explanation:

We have to find the length of segment VW.

Coordinates of the points W are (-4, -2) and coordinates of V are (-2, 2)

Now we know the formula to get the length of VW.

VW =
`\sqrt{(y-y')^(2)+(x-x')^(2)}`

=
`\sqrt{(2+2)^(2)+(-2+4)^(2)}`

=
`\sqrt{4^(2)+2^(2)}`

=
`√(16+4)=√(20)`

= 2√5

= 4.47 units

Therefore, the length of VW = 4.47 units
