I'm assuming that the signs inside each circle is its sign. So, negative sign in the circle means it is a negative number and vice versa.
a.) Given:
7 circles w/ negative signs, 4 out of 7 circles are crossed out.
- 7 - 4 = -11
b) Given:
7 circles with positive sings and 5 circles with negative signs. The 5 negative circles are crossed out.
+ 7 - (-5) = 7 + 5 = 12
I'm not sure if I am correct but I answered based on what I understand from the given data.
Answer:
the correct answer is D
Step-by-step explanation:
AB^2 + BC^2 = AC^2
AB^2 + 6^2 = square root 117^2
AB^2 + 36 = 117
Now subtract 117 from both sides
AB^2 = 81
AB = square root 81 = 9

Therefore AB is 9 cms.
