1, because when you multiply 52 and 4 (the number of sides) to get the total square feet of the ceiling, you get 208 square feet, which is exactly how much 1 can of paint will cover

Answer:
37 is the smallest positive integer n such that n(n+1)(n+2) is divisible by 247.
Step-by-step explanation:
First we will find the prime factors of 247:
247 = 13 x 19 (which are both prime).
So now we need to find a number (the smallest one) that is of the form (n)(n+1)(n+2) (the product of three consecutive numbers) and that is divisible by both 13 and 19 (and therefore divisible by 247)
Let's take a look at the multiples of 13: 13, 26, 39, 52...
Let's take a look at the multiples of 19: 19, 38, 57...
We can see that the first time we have two multiples close together are the 38 (for 19) and the 39 (for 17).
So, if our number has both 38 and 39 as factors, then it will be divisible by 247.
However, we need not two but three consecutive numbers, and since we want the number to be the smallest positive integer, we will add 37 (since our other choice would be to add 40 and that would make the number bigger) and thus our number is (37)(38)(39) or in other words (37)(37 + 1)(37 + 2) and therefore this is the smallest positive number such that n(n+1)(n+2) is divisible by 247.
Answer.
1) False
2) False
3) False
Explanation
1) When a number is written as a+bi, a and b are real number. b is never considered as imaginary number.
The statement given is false.
2) The value of i is √(-1), when squared we get;
(√(-1))² = -1.
The answer given is false.
3) It is not possible to graph a complex number is XY coordinates. Complex number are graphed on an imaginary axis and real axis only.
The statement given is false.
The answer is geometric.
Hope this helps !
