Hi,
Following the rules of PEMDAS you first subtract in the parentheses.
(5-2)=3
Then multiply the parentheses.
(3)(-6)=-18
Solve the exponent.
-4^2=16
Then you add -18 and 16 to get -2.
So the answer is B.-2.
I hope this helps.
The angles must be opposite to be equal to each other so parallelogram ABCD
Line AB is parallel to DC and line AD is parallel to BC
C is the correct answer
