Answer:
x - 9 = ±9
Step-by-step explanation:
We have been given the following equation;
(x-9)^2=81
We are to determine the resulting equation after taking the square root of both sides.
The square root of the expression in the left hand side is;
((x-9)^2)^(1/2)
The square and square root are inverse functions and as such they simply cancel out yielding;
x-9
Now, the square root of 81 is simply ±9 since 9*9 = 81;
9^2 = 81
Thus the square root of 81 is ±9. The resulting equation is thus;
x - 9 = ±9
This can be simplified by adding 9 on both sides of the equation to yield;
x - 9 + 9 = 9 ± 9
x = 9 ± 9
x = 9 + 9 = 18 or x = 9 - 9 = 0
x = 18 or x = 0

246/12,8/12,3/12,3/12,6/12,84/12, In order is like this
246/12,84/12,8/12,6/12,3/12
41/2>21/3>2/3>1/2>1/4 0r
1/4<1/2<2/3<21/3<41/2
Im assuming by 5-.8, you mean 5/8ths and by 1-.4, you mean 1/4th...
x=5/8+1/4
x=5/8+2/8
x=7/8
They ate 7/8 together
