What number is smller than 40 when you double it and take away 9 you get a square number?
It is easier to tackle this by writing it in algebraic form:
2a - 9 = b
Where a is a number smaller than 40 and b is square.
There are way more numbers less than 40 than there are relevant square numbers, so it's best to solve this for a:
2a = b+9
a = (b+9)/2
b can be 1, 4, 9, 16, 25, 36, 49, 64, 81, 100...
If b is even, then (b+9)/2 will not divide evenly, so this limits us to 1, 9, 25, 49 and 81
For 81, (b+9)/2 = 45 which is more than 40, so b can only be 1, 9, 25 or 49.
Plugging these into the equation means that a can be 5, 9, 17 or 29

Why is when you subtract 1 from the square of an odd number it is even?
An odd number multiplied by another odd number will always equal an odd number. Therefore odd2 = odd x odd = odd number. eg 32 = 3 x 3 = 9. Take away 1 and you will have on even number.
What does subtracting mean?
subtraction means you have to take away from the number
What does Pythagoras' theorem involve?
Pythagoras' theorem is basically a method to find a missing length of a triangle. So you have side A, B and c. Side c is opposite the right angle in the triangle (right angled triangle) If you square A and B and add them together you will get a number. You then square route that number and that will be the length of side C. As it is opposite the right angle it will be the longest side. If you want to find one of the shorter sides for example A you square C and take B away from it. You then square route this number. If you have a scientific calculator there will be a square and square route symbol. The square symbol is a little two and the square route one is like a tick but the top goes across into a line, if that makes sense. Hope this has helped.

Double a number is 3 more than a number?
Let's denote the number as x. The statement "double a number is 3 more than a number" can be mathematically represented as 2x = x + 3. By solving this equation, we find that x = 3. Therefore, the number in question is 3.

When asked on an application which number best completes the sequence 1 1 3 2 4 6 5 25?
I think the sequence is square the first number, add two, take away one, square that number, add two, take away one, square that number. 12 = 1, 1 plus 2 = 3, 3 minus 1 = 2, 22 = 4, 4 plus 2 = 6, 6-1 = 5, 52 = 25. This would mean that the next number in the sequence is 27 because the next step would be to add two.
What is the square number closest to 1000?
Thirty-one is the closest square to 1000.Actually unless the Q was "What's the square number closest but less than 1000? then you would be right if only half right as your awnswer should have been 961.But it's not that so...as the Q has been written the answer is 1024.312 = 961 (39 away from 1000)322= 1024 (24 away from 1000)
