Arectangular meeting room (2 + 1) feet wide and (5 + 7) feet long needs to be repainted.
the height of the room is the same as the width. the walls of the room have four glass windows,
each measuring 3 feet by 2 feet and two wooden doors, each measuring 3 feet by 7 feet. ignoring
the ceiling and floor, what expression represents the area of the walls that needs to be painted?

7! = 7×6×5×4×3×2

3! = 3× 2

as 7! is multiple of 3! because 7! contains 3! that is 3× 2 as factor

so 7! /(3! ) = 7× 6× 5× 4

= 42 × 20

= 840

its b) 840✌✌✌

aloha~! my name is zalgo and i am here to you out on this amazing day. to answer your question, yes, nonzero numbers can have a greatest common factor and that would be 1. still don't get it? let me considering every number is divisible by 1 and hence every number has 1 as a factor of theirs. so, if 2 nonzero numbers didn't share any gcf (greatest common factor), they would still have a factor in common and that would be 1.

i hope that this ! : p
