An experienced maid can clean a room in 30 min. a new maid can clean the same room in 60 min. how long will it take if both maids work together?

30+60/2
= 90/2
= 45 mins

I think it will take 45 minutes because 30/2 = 15 and 60/2 = 30.
So, 30 + 15 = 45

No a triangle cannot be formed because when you add the two smallest number together (which would be 11) the have to be bigger than the number it is "against" ( which would be 12)

A’b’c’ are the coordinates to the new location of the transformed triangle abc. find the distance between the coordinates points to use for your calculations.
