2.1-2p= -4.7

they said the difference of 2.1 and twice a number p. which I'm assuming letter p, but anyway. difference means subtraction and twice mean multiplication so 2p

that's why we have 2.1-2p= -4.7

Which statement is true?
ANEK [815]

Option B:

A ray has two endpoints and extends infinitely in both directions.

Solution:

Option A: Two lines that intersect are called skew lines.

It is false because,

Two lines are said to be skew lines if they do not intersect and do not lie in the same plane.

Option B: A ray has two endpoints and extends infinitely in both directions.

It is false because,

A ray has one endpoint and extends infinitely in one direction.

Option C: A line is a set of points that extends infinitely in both directions.

It is false true.

A line is a set of points that extends infinitely in both directions.

Option D: Two lines in the same plane are said to be perpendicular if they never intersect.

It is false because,

Two lines are said to be perpendicular if they are intersect.

Hence Option B is true. A line is a set of points that extends infinitely in both directions.

How do I solve 14x+5=105
Stella [2.4K]

Answer:7.14

Don’t rely on me I tried. Might be wrong but there’s an app called photo math and it’ll help with equations just like this.

Step-by-step explanation:subtract 5 from 5 and subtract 5 from 105 because you want to get X by itself. There for 14x equals 100. Then divide both by 14. 14 cancels out and you get your answer.
