Answer: 5

explanation:

x -5 apples = x^2 - 25

1 apple = x

cross multiply:

x (x-5) = 1 (x^2 - 25)

x^2 - 5x = x^2 - 25

the "X^2" WILL CANCEL OUT

-5x = -25

x = -25/-5

x = 5

The cost of one apple is x + 5

Let the cost of one apple be y.

So, we have the following equation

y * (x - 5) = x^2 - 25

Express x^2 - 25 as a difference of two squares

y * (x - 5) = (x + 5)(x - 5)

Divide both sides by x - 5

y = x + 5

Hence, the cost of one apple is x + 5
