He can because you can add it mentally. You can just have 23 in your head and count by adding 10 "4" times.
Hope this helped☺☺
Answer: Parallel lines are lines in a plane which do not meet; that is, two straight lines in a plane that do not intersect at any point are said to be parallel. Colloquially, curves that do not touch each other or intersect and keep a fixed minimum distance are said to be parallel.
Answer:
Here is it given 52 men can do a piece of work in 35 days .
Which means total work is 52*35
Therefore total work = 52*35 = 1820.
Now 28 men are alloted to do same work
Let's consider the days taken by 28 men is x
We cans say that 28 men take x days to complete the work
28 * x = 1820
x = 1820/28
x = 65
By definition, skew lines are a pair of lines that are not parallel but do not intersect each other either. Hence, the conclusion would be, the lines are non-coplanar. An example would two random lines drawn in the x and y axes in a cartesian plane, respectively.
