Answer:
x=27
Step-by-step explanation:
The mean is add all the numbers and divide by the number of points
(2+7+x)/3 =12
Multiply each side by 3
(2+7+x)/3 *3 =12*3
2+7+x = 36
Combine like terms
9+x = 36
Subtract 9 from each side
9+x-9 = 36-9
x = 27
Answer:
D) n^6 - 6m^6 + 7mn^5 + 14m^2n^4 -5m^3 n^3
Step-by-step explanation:
The given polynomial is 8mn^5 -2m^6 +5m^2 n^4 - m^3 n^3 + n^6 - 4m^6 + 9m^2n^4 -mn^5 - 4m^3n^3
Now we have to identify the like terms and simplify.
Like terms are nothing but the terms which have the same variables with same powers.
= (8mn^5 - mn^5) -2m^6 - 4m^6 + 5m^2 n^4 + 9m^2 n^4 - m^3n^3 - 4m^3n^3 +n^6
Now combine the like terms
= 7mn^5 - 6m^6 +14m^2 n^4-5m^3n^3 + n^6
It can be written in standard form
= n^6 - 6m^6 + 7mn^5 + 14m^2n^4 -5m^3 n^3
The answer is D)
Hope this will helpful.

Consider the number 38,288
Now, we have to round this number to the nearest hundreds place.
The place value to the extreme right of the number is ones, then tens, hundreds, thousands, ten thousands and so on.
So, the digit at hundreds place = 2
Consider the digit to the right of the hundred place which is '8', which is greater than 5.
Therefore, we will add '1' to the digit at hundreds place.
Therefore, the number 38,288 rounded to nearest hundreds is 38,300.
If your scale factor has absolute value greater than 1, the dilation is an enlargement.
