(2n-1) /(n+9)
hope it can help u
The mean would be 5
Reason for this is that the mean is when all data is summed up then divided by how many data points there are
So 4+4+7=15
Then divide by 3 would equal 5
I hope this helps!
Answer:
A. Right Triangle
D. Isosceles
Step-by-step explanation:
Well, since it has a square at the bottom of the triangle, it means it's a right triangle, because it has a 90 degree angle.
It is also an isosceles triangle, because two of the sides are of equal length.
Hope this helped!

(29-22)*26+(26-21)*22
Cut the figure into 2 then find the unknown lengths to find each part. Add them together, and you'll get the answer.
-7+(9)=2
you can do the opposite of what is given (9-7)
