The numbers are 55, 56 and 57 OR 54, 56 and 58
57 is a rational number
It is 260.
This is the commutative property. In symbols a+b = b +a and ab=ba for any numbers a and b.
None, since 57 is NOT an irrational number.
The sum of the first 57 natural numbers is 1,625.
The sum of 57 is 57 itself. In mathematical terms, the sum refers to the result of adding two or more numbers together. Therefore, when you add 57 to another number or to itself, the sum will be the total value of those numbers, which in this case is 57.
A single number can have only one sum: in this case, 57.
No.
57
x+21 = 57
The sum of two evens is even so the sum of any number of evens is even. It is, therefore, impossible for the sum of three even numbers, whether or not consecutive, to be 57, which is an odd number.
57
57.
The way you actually wrote it: x+2(57). This is just x+114 and does not help you find x.The way I think you meantto write it: x+2x=57. 3x=57. x=19
An even number less than 57.
57 or 75
