Answer:
Solution given:
the equation of a circle is:
x²+y²-6x-2y+4=0
x²-2*x*3+3²+y²-2y+1²-1²+4=0
(x-3)²+(y-1)²=9+1-4
(x-3)²+(y-1)²=6
comparing above equation with
(a-h)²+(y-k)²=r²
we get
centre (h,k)=(3,1)
radius=√6
option first
<u>(3,1), r = </u><u>√</u><u>6</u><u> </u><u>is</u><u> </u><u>a</u><u> </u><u>required</u><u> </u><u>answer</u><u>.</u>
Answer:
Yes
Step-by-step explanation:
Algebraic terms that multiply each other can be written in any order. This is the commutative law.
An example of how this works is 5×3 is the same as 3×5.

Answer:
Step-by-step explanation:
3(m-2)+2(m-2)
3m-6+2m-4
3m+2m-6-4
5m-6-4
5m-10
The expressions 3(m-2)+2(m-2) and 50m-2 are not equivalent expressions.
After simplifying the first expression 3(m-2)+2(m-2) in part (a), we got 5m-10, which is different from the second expression, 50m-2.
