Answer:
d
Step-by-step explanation:
when the equation is written out, you get 
the square root of 8 can be rewritten as 2 times the square root of 2. if you distribute the root two into the parenthesis you get 5 root two plus 4, because two root two times two comes out to two times two which is four. so your answer is d, 4 + 5 sqrt 2
The answer is 42, 12(12.5) - 3(6) ^2 / which is 36 so it’s 12(12.5) - 36 so simplistically it’s 150-36 and that’s 42
