For the following figure, complete the statement for the specified points.
maria [59]

Answer:

option 4 - Points R, S, and T are neither collinear nor coplanar.

Step-by-step explanation:

Given : Statement 'Points R, S, and T are' and figure is attached.

To find : Complete the statement for the specified points ?

Solution :

Collinear points is defined as points all in one line.

Coplanar points is defined as  points all in one plane.

As point R,S,T not lie in the one line.

So, Points R, S, and T are non-collinear.

Now, point R,S,T not lie in same plane also.

As we draw a plane horizontally then R point not lie.

As we draw a plane vertically either S or T will not include.

So, Points R, S, and T are non-coplaner.

Therefore, Points R, S, and T are neither collinear nor coplanar.

Hence, option 4 is correct.

Write a two step equation that has -5 as it solution.
DaniilM [7]

-3b-4=11

-3b-4+4=11+4 (Move constants to the right by adding its opposite to both sides)

-3b=11+4 (Eliminate the opposites)

-3b/(-3)=15/(-3) (Divide by -3 on both sides)

b= (-5)
