Answer 2

Answer:

Lets assume the two numbers as x and y

As given in the question:

x-y = 75

x+y = 2(87.5)or

x+y = 175

since x-y = 75......equation 1

x+y = 175........equation 2

x = 175-y

we will substitute the x value in the

equation 1

therefore:175-y-y = 75

175-2y = 75

175-75=2y

100=2y

y = 50

then x-50 = 75

x = 125

x²-y²=?

125²-50²=?

15625-2500 = 13125

therefore the answer would be 13125
