Find the greatest common factor (GFC) for this pair of composite numbers. 10 and 15

Given:

The pair of composite numbers: 10 and 15

To find:

The greatest common factor (GFC) for the given pair of composite numbers.

Solution:

Two composite number are 10 and 15.

The factor forms of these two numbers are

It is clear that the common factor is 5 in both factor forms. So, the greatest common factor is

Therefore, the greatest common factor of 10 and 15 is 5.

after simplifying it i got: -36.25 as my answer. hope that !

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
