Answer:
1.) Yes
2.) Yes
Step-by-step explanation:
Given that
n = k(k + 7)
If k is a positive integer and n = k(k + 7), is n divisible by 6 ?
(1) k is odd. Yes.
Let assume that k = 3
Then, n = 3(3 + 7)
n = 3 × 10
n = 30.
30 is divisible by 6.
(2) When k is divided by 3, the remainder is 2. That is,
Let k = 5
Then,
5/3 = 1 remainder 2
Substitute k into the equation
n = k(k + 7)
n = 5(5 + 7)
n = 5 × 12
n = 60
And 60 is divisible by 6.
Therefore, the answer to both questions is Yes.
It would be 3 with be on the side and then 2/10
Answer:
the answer is 3
Step-by-step explanation:
in the number 66 there are "2" circles in them and so the answer we get 2
in the number 99 there are "2" circles and so the answer there is 2
in the number 888 there are "6" circles so the answer is 6
in the number 00 there are "2" circles that's the answer
in the number 7777 there are no circles so the answer is 0
we keep on going like that......
in the number 2876 there are 3 circles 2 in the number 8 and 1 in the number 6
hope this helped :D
