Answer:
12x^2+2x+7
Step-by-step explanation:
Distribute the Negative Sign:
=4x^2+6+7+−1(−8x^2−2x+6)
=4x^2+6+7+−1(−8x^2)+−1(−2x)+(−1)(6)
=4x^2+6+7+8x^2+2x+−6
Combine Like Terms:
=4x^2+6+7+8x^2+2x+−6
=(4x^2+8x^2)+(2x)+(6+7+−6)
=12x^2+2x+7
Use grid paper to find the median of the data.<br>

You want to put the numbers in order from least to greatest like this-
0,2,3,3,4,5,6,7,8,8,9,9
then you want to start from the left end and the right end then you start crossing them off until you have a median, you keep crossing off until you get 5 and 6 in the middle, now you have to find the mean of the two numbers you add them together than you divide by 2 like this- 5+6=11 11/2=5.5
5.5 is your answer
