Pre-image =Rectangle EFGH
Image = Rectangle E'F'G'H'
Stretch Factor = 2.5
Coordinates of Point H= (-2,0)
If Coordinate of any point is (x,y) and it is stretched by a factor of k , then coordinate of that point after stretching = (k x , k y).
So, Coordinates of Point H' will be=(-2×2.5,0×2.5)
= (-5,0)
Find the least common multiple of 3 and 5:
3: 3,6, 9,12,15,18,21
5: 5, 10, 15, 20
The least common multiple is 15. This means every 15 days they will be the same day.
Add 15 days to May 5:
5 + 15 = 20
The next day would be May 20
