CAN SOMEONE PLSSS HELP WITH 27 , 28,29!

djverab [1.8K]

The area for 27 is 64cm^2.

For the mean, you add up all the numbers then divide by how many numbers there are. So you would do 45+96+100+39+50 and divide it by 5. So your mean is 66.

Now for 29.
For when n=5 is 8
For when n=8 is 14
For when n=14 is 26

Hope this helps!

3 + 3(k + 3) = 6(k - 2) +9

ANTONII [103]

Step-by-step explanation:

3 + 3(k + 3) = 6(k - 2) + 9

3 + 3k + 9 = 6k - 12 + 9

12 + 12 - 9 = 6k - 3k

15 = 3k

k = 15/3

k = 5
