Answer:
1st question's answer I don't know and 2nd question's answer is 37.1
Step-by-step explanation:
Mean= sum of all the terms/no. of terms
=12.5+38.3+16.3+2+145+8.5/6
=222.6/6
=37.1
The answer is to your question is x^2 - 8x
The easiest place to start is with the answer. The 3 by 4 rectangle (upper right) is the answer. P = 2(L + W) = 2(4 + 3) = 2*7 is 14.
14 is less than 16.
Now lets find out why the others can't be true.
The upper left has an area of 12 (6*2). So the area is find.
P = 2 * (L + W) = 2* (6 + 2) = 16 This would support the conjecture so it is not the answer you want.
The lower left has an area of 12 and a perimeter of 2*(12 + 1) = 26. That supports the conjecture. So you don't want that one either.
The lower right does not have an area of 12. It cannot help us at all.
The answer should be B. Incenter
