You have to click the blue, then red, then blue, then yellow :)

### Is there a perfect cube of 56?

The question could ask for the perfect cube of 56, which equals 563 = 175616. However, it can also mean to ask whether 56 can be a cube, which could be answered by 56(1/3), which cubed is 56. Since 56(1/3) is an irrational number, it is impossible to construct this perfectly, but one can make arbitrary precise approximations, close to 3.825862365...

### What is three eighths minus one seventh?

If working in fractions, then you must make the fractions have the same denominator (the number on the bottom). To decide what the denominator should be you find what number does 8 and 7 go evenly into (8 x 7=56). Therefore 56 is the new denominator, now you must make the fractions in the question equal the same amount with a denominator of 56. WHAT EVER YOU DO TO THE DENOMINATOR YOU MUST DO TO…

### What is the factorization for y equals x2 x equals 56?

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "equals" etc. And using ^ to indicate powers (eg x-squared = x^2). If the question is x2 + x = 56 then the factorisation is (x - 8)(x + 7) If the question is x2 - x…

### What is 56 21-31 100 96-1?

Unfortunately, limitations of the browser used by Answers.com means that we cannot see most symbols. It is therefore impossible to give a proper answer to your question. Please resubmit your question spelling out the symbols as "plus", "minus", "times", "divided by" etc. Here there are no operators after 56, 31 and 100.

### What is the missing number in the sequence 68 56 50 40?

The answer depends on which number is missing. The sequence could be: 96, 68, 56, 50, 40 68, 61, 56, 50, 40 68, 56, 522/3, 50, 40 68, 56, 50, 46, 40 68, 56, 50, 40, 16. In fact, there are infinitely more possible answers. Given ANY fifth number to add to the four in the question, it is always possible to find a quartic (power 4) polynomial that will fit all five numbers.
