Please help I need it done right now

Use the way that kids use i.e trial and error method .

Solution:-

The set given by

Lets understand

Come to 2nd one.

Come to third one

Lets think

Nearest squares to 225 are 196 and 289

We can't take 196 as we have to take a positive one other wise it will come in terms of i.

Take 289

Its divisible by 8 .

Rewrite the set

Hence n=64

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
