Answer:
-16/3
Step-by-step explanation:
To solve for this use the mnemonic device PEMDAS (parenthesis, exponent, multiplication, division, addition, subtraction)
First multiply -4 and 2 (-8)
(-8)^2/2-9-5
Next find out what -8 squared is (64)
64/2-9-5
Now simplify the denominator
64/-12
Lastly, divide 64 and -12
-16/3
