Answer : A
A. 3 × (2 × 6) = 36
we have 3 times 2 times 6. All the numbers have multiplication in between . so it comes under Associative property of multiplication.
B. (3 + 2) × 6 = 30
we have 3+2 . there is a + sign in between. so it does not comes under Associative property of multiplication
C. 6 + (5 × 6) = 36
we have 6 + . there is a + sign in between. so it does not comes under Associative property of multiplication
D. 3 × (2 + 6) = 24
we have 2 + 6 . there is a + sign in between. so it does not comes under Associative property of multiplication

Answer:
C ) circle
This equation represents circle
x²-2 x+y²+4 y - 31 =0
Step-by-step explanation:
<u><em>Explanation:-</em></u>
let P(x₁ , y₁) be the locus point
Let P(x₁ , y₁) and A(1,-2)
Given data PA = 6
PA² = 6²
( x₁ -1 )²+(y₁+2)² = 36
x₁²-2 x₁+1+y₁²+4 y₁ +4 = 36
x₁²-2 x₁+y₁²+4 y₁ = 36-5
x₁²-2 x₁+y₁²+4 y₁ - 31 =0
This equation represents circle
x²-2 x+y²+4 y - 31 =0
