Answer:
x = a³b + b²/ab + 1
Step-by-step explanation:
x = a² + b²/ab + 1
x = a² × (ab + 1) + b²/ab + 1
x = a³b + a² + b²/ab + 1
x = a³b + b²/ab + 1
Okay wait what how i do this mark me brainless 0
Firstly , we will locate centres and radius in the figures
(a)
We can see that
centre=(h,k)=(0,0)
radius=r=5
now, we can use standard equation of circle

we can plug values
we get


(b)
We can see that
centre=(h,k)=(5,4)
radius=r=3
now, we can use standard equation of circle

we can plug values
we get


(c)
We can see that
centre=(h,k)=(4,3)
radius=r=5
now, we can use standard equation of circle

we can plug values
we get
