5 100ml cups and 1 500 ml cup
and 2 500 ml cups
List the factors of 24,30, and 24. Factors of 24: 1,2,3,4,6,8,12,24. Factors of 30: 1,2,3,5,6,10,15,30. Factors of 42: 1,2,3,6,7,14,21,42. The highest number that all of these numbers is 6. Therefore, the greatest common factor of GCF of 24,30, and 42 is 6.
The hypothenuse is the opposite side of the right angle
so that means that in this triangle the hypotenuse is 7

is in quadrant I, so

, which means

, so

belongs to the same quadrant.
Now,

Since

, it follows that

Since

belongs to the first quadrant, you take the positive root (

for

in quadrant I). Then


is also positive for

in quadrant I, so you take the positive root again. You're left with
Between 4 and 6 is where u put the grouping symbols!
