This is a very poorly worded question.
It does not specify how many numbers.
"give an integer of -13" is a meaningless phrase. Is that when added together, one subtracted from the other, multiplied together, one divided by another, one raised to the power of another, etc.
As a result, it is impossible to work out what the question means and so it cannot be answered.
Yes, all negative whole numbers, including -13, are integers.
-13 is an integer.
Let's call the two integer numbers x and y. We know that xy = -26 and x + y = -11. By trying different combinations, we find that the numbers -13 and 2 satisfy both conditions, as -13 multiplied by 2 equals -26 and -13 plus 2 equals -11. So, the integer pair is (-13, 2).
Integer.
-13 is already an integer. It corresponds to the absolute value 13.
The numbers are: 4 -sq rt of 13 and 4 +sq rt of 13
420 cm = 13' 9.4"
Since both 13 and 41 are prime, the only common positive integer that is shared by the two numbers is 1.
No integer other than 1 does. Numbers like this are said to be co-prime.
420 centimeters is 13 feet and 9.35 inches.
