Answer: the answer is 9 duhh
Step-by-step explanation:
Answer:
centre= (2,-3)
radius=2
equation= (x-2)^2+(y+3)^2= 4
Step-by-step explanation:
equation is found by the co-ordinates and the length of the radius
if the co-ordinates (2,-3)
x=2
y=-3
r= 2
so the equation will be like
=(x-2)^2+(y+3)^2=2^2
=(x-2)^2+(y+3)^2=4
Thankyou ^^
We are told that l is the length of the rectangle. We are told that the widht is 4 less than half the lenght. So, first, we calculate the half of l, which would be

the part that says "4 less than" means that we should subtract 4 from the half of length. So we get

now, this expression should be equal to the width , that we'll note as w. So we end up with the equation
