Question

can x^2+y^2=25 be written as x+y=5 ?​

Answer 1

Answer:

true, x^2+y^2=25 can be written as that since square of 5 is 25 and x squared and y squared gets cut off to x+y

Step-by-step explanation:

written above

Answer 2

Answer:

No.

Let x= 3, then x^2 = 9.

Let y=4, then y^2 = 16.

Here x^2+y^2 = 9+16=25.

But x+y = 3+4, which is not equal to 5.
