Answer:
x =
Step-by-step explanation:
The question states that it is the square root of the sum of both n and 6. That means n and 6 are added first before square rooted. Between B and C, choose the answer that has the parenthesis around x and 6, like (x + 6).
Let
y=2x-10
Switch x and y,
x=2y-10
x+10=2y
(x/2)+5=y
So
57, 58, 59, 60
Hope this Helps :)
