Hello! Combining like terms is just a fancy way of saying add all these numbers together. As long as numbers have the same variable (in this case x) and the same exponent (they don't have any in this case), you can add them together like normal. So! 3x + 5x +4x is the same as 3+5+4. Your simplified polynomial is 12x. Good luck with the math homework!
The median is the middle number in a set of data, or the arithmetic mean of two middle numbers if there is even number of elements in the set.
Sort the numbers from least to greatest:
5, 7, 11, 13, 14
The median is 11.
A. If you add {2, 19}:
2, 5, 7, <span>11</span>, 13, 14, 19
The median is 11.
B. If you add {6, 12, 16}:
5, 6, 7, 11, 12, 13, 14, 16
The median is the mean of 11 and 12.
(11+12)/2=23/2=11.5
The median is 11.5.
C. If you add {6, 11, 15}:
5, 6, 7, 11, 11, 13, 14, 15
The median is the mean of 11 and 11.
(11+11)/2=22/2=11
The median is 11.
D. If you add {3, 4, 14}:
3, 4, 5, 7, 11, 13, 14, 14
The median is the mean of 7 and 11.
(7+11)/2=18/2=9
The median is 9.
In A and C the median of the new data is the same as the original median, in D it's less than the original median, only in B it's greater.
You can add {6, 12, 16} to the data to increase the median.
The answer is B.
Answer:

Step-by-step explanation:
Answer:
8,900
Step-by-step explanation:
Given Number: 8,937.2546
Determine the two consecutive multiples of 100 that bracket 8,937.2546
8,937.2546 is between 8,900 and 9,000
8,950 is the midpoint between 8,900 and 9,000
As illustrated on the number line, 8,937.2546 is less than the midpoint (8,950)
Therefore, 8,937.2546 rounded to the nearest hundred = 8,900
