Answer:

(x+3)^2 + (y-4)^2 = 64

Step-by-step explanation:

We can write the equation of a circle as

(x-h)^2 + (y-k)^2 = r^2  where ( h-k) is the center and r is the radius

(x--3)^2 + (y-4)^2 = 8^2

(x+3)^2 + (y-4)^2 = 64

Kat = 2/5

Sanjeev = 3/5

The amount that each collects will be:

= 2 × £51

= £102

Sanjeev = 3/5 × £255

= 3 × £51

= £153

To solve this, you cross multiply, then divide. In this case, we multiply 4 and 2, then divide by 3.

4 x 2 = 8
8 / 3 = 2.66

So, x is 2.66
