Step-by-step explanation:
Alright, lets get started.
Suppose the first fraction is : 
Suppose the second fraction is : 
The sum of both fraction is given as : 
.......................equation (1)
The difference of both fraction is given as : 
.........................equation (2)
Adding equation (1) and equation (2)


making common denominator


Hence,

Plugging the value of
in equation (1)

Subtracting
in both sides


Hence both fractions are

Answer:
28
Step-by-step explanation:
The diagonals of the parallelogram are AC and BD. The way the diagram is drawn, BD is the long diagonal, said to be 24 inches. AC is the short diagonal, said to be 12 inches.
Since AC bisects BD at point E, point E is the midpoint of BD. That means BE = (24 inches)/2 = 12 inches.
Since BD bisects AC at point E, point E is the midpoint of AC. That means EC = (12 inches)/2 = 6 inches.

Now, we know the lengths of the sides of ΔBEC, so we can find its perimeter. The perimeter of any geometry is the sum of the lengths of its sides.
perimeter ΔBEC = CB +BE +EC
perimeter ΔBEC = 10 in + 12 in + 6 in = 28 in
The perimeter of triangle BEC is 28 inches.
