Q: What 2 equal numbers have the sum 54?

Write your answer...

There are no two real numbers that do, but two complex numbers that do are: (3 + i√45) and (3 - i√45). If the numbers multiply to -54 and sum to 6, then two numbers that do are: (3 + √63) ≈ 10.937 and (3 - √63) ≈ -4.937 If the numbers multiply to -54 and sum to -6, then two numbers that do are: (-3 + √63) ≈ 4.937 and (-3 - √63) ≈ -10.937

No

54 and 54

The numbers are 54 and 56.

2 and 3 2x3x3x3= 54

no

17 and 37. 17+37=54

16

It is: 2*3*3*3 = 54

-27 and -2

29 & 41

no 2 is a prime number

65

Addends or summands.

2 and 17

Yes: 1 + 1 = 2.

The sum of two positive mixed numbers can not equal two because all positive mixed numbers are greater then one.no two can be, 1 1/2 and 1/2

45 and 54

1 and 54 - added together.

2 x 3 x 3 x 3 = 54

2, 3, and 13 are all prime numbers and their sum is equal to 18.

There are none.

83 + 2

-31

Yes. Mixed numbers can be negative. -11/2 + 31/2 = 2
