~Please ~ help ~ me ~ with ~ these ~ questions.~ You don't need to answer both, but at least answer one.
If you DO answer both you get Brainliest ^^

First Question

A is not correct. If you have one point, you wouldn't know where the line would extend. You need at least two points to determine a line. You need at least three points if you don't know if the line is linear.

B is correct. A ray has one endpoint and extends infinitely in one direction.

C is not correct. A line segment has two endpoints and does not extend infinitely.

D is not correct because a line is infinitely extending. It has no endpoints.

Second Question

A is not correct. Skew lines are two or more lines that do not intersect, are not parallel, and are not coplanar.

B is correct. Perpendicular lines must intersect at a right angle.

C is not correct. Two parallel lines can lie in the same plane.

D is not correct. A transversal is a line that intersects two or more other lines. This does not have to be four other lines (but it can).

your answer is 23/2 - 13.5

step-by-step explanation:

7/2 evaluates to

multiply x and 4.5

multiply x and 1

the x just gets copied along.

the answer is x

x

4.5*x evaluates to 4.5x

multiply 3 and 4.5x

multiply 1 and x

the x just gets copied along.

x

4.5*x*3 evaluates to 13.5x

7/2-4.5*x*3 evaluates to

  + 8 =

the answer is

7/2-4.5*x*3+8 evaluates to
