A cord is cut into two pieces of different lengths. The sum of the two lengths is 6 centimeters, and the difference between the two lengths is 4 centimeters. Find the lengths of the two pieces of cord.

5 and 1 cm.

Step-by-step explanation:

1. 3 and 3 don't work through subtraction.

2. 4 and 2 don't work through subtraction.

3. 5 and 1 work through subtraction and addition! (ANSWER)

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
