Answer:
real, rational
Step-by-step explanation:
Without knowing what the average number of students is, we know the number must be a real number, and must be rational. (An average of integers is always the ratio of two integers.) It may or may not be a natural number, whole number, or integer.
Answer:
35 degrees.
Step-by-step explanation:
In order to find an angle in a triangle we need to know the other two angles, because the angles in a triangle all add up to 180 degrees. So, knowing two will get us the other one. In this case, we know two angles. One of them is 55, and the other, since it is a right triangle, is 90. So the two angles we know are 55 and 90. Using that all angles in a triangle add up to 180, we can use
55 + 90 + x = 180
145 + x = 180
x = 35
Answer:
9,400
Step-by-step explanation:
12,846 - 3,467 = 9,379
The hundreds digit is 3.
So, you look to the left of the digit and if it is 5 for more you add a number to the 3 and make the rest of the digits 0s. But if it below 5, then you leave the 3 alone and make the rest of the digit going to the right 0s.
Then, your answer is (9,400)

Answer:
6x^2 ( x^2 -2) ( x^2 +2)(x^2+2x+2)(x^2-2x+2)
Step-by-step explanation:
6x^10 − 96x^2
Factor out 6x^2
6x^2 ( x^8 - 16)
Notice that inside the parentheses we have the difference of squares
6x^2 ( x^4 ^2 - 4^2) a^2 - b^2 = (a-b) (a+b)
6x^2 ( x^4 -4) (x^4 +4)
Notice that x^4-4 is also the difference of squares
6x^2 ( x^2^2 -2^2) (x^4 +4)
6x^2 ( x^2 -2) ( x^2 +2) (x^4 +4)
Note also that x^4 + 4 can be factored into (x^2+2x+2)(x^2-2x+2)
6x^2 ( x^2 -2) ( x^2 +2)(x^2+2x+2)(x^2-2x+2)
Answer:
12.66666 infinity or 38/3
Step-by-step explanation:
Parentheses first so 5-2 is 3... then multiply so then 12... 12+32-6 is 38. 38 over 3 is 12.6666 infinity or 38/3, cannot be simplified...
