HELP ME PLZ IN NEED THIS DONE BY 8:10

Answer 16.
Step-by-step explanation:
First you replace the xs with 1/2
(√2•1/2+3)/(6•1/2-5)
Then you solve the multiplications
2•1/2=1
6•1/2=3
Now write them in
(√1+3)/(3-5)
Simplify
(√4)(-2)
Root of 4 equals to
2/-2
And the answer is -1
Answer 17:
Replace x with 8
1/2•8^2-(1/4•8+3)
Solve parenthesis, multiplication first
1/2•8^2-(2+3)
1/2•8^2-(5)
1/2•8^2-5
Solve the 8^2 and the 1/2
1/2•64-5
32-5
The answer is 17
