n is an integer, so 2n+1 is also an integer. 8s+1 is equal to the square of 2n+1, so it's a square number.
2n+1 is an odd integer for any value of n. The square of an odd integer is always an odd integer. Therefore 8s+1=(2n+1)² is odd.
8s+1 is an odd square number.

Question:
Which of the following represents two lines that are coplanar and do not intersect?
A. Perpendicular
B. Skew
C. Parallel
D. Intersecting
Answer:
Two lines that are co -planar and do not intersect is Parallel.
Step-by-step explanation:
Two lines are said to be parallel if they lie in the same plane, and are the same distance apart over their entire length.Each line has many parallels. Any line that has the same slope as the original will never intersect with it. Hence Parallel Lines would never cross, even if extended forever. Technically parallel lines are two coplanar which means they share the same plane or they're in the same plane that never intersect
see so,1200 kg of coal=1kg of aluminum
if 1 soda can needs 15g of aliminium so
1200/15=80kg coal will be needed for 1 can of soda.
