ANSWER
D. x=55
EXPLANATION
The given radical equation is

Add -3 to both sides


Square both sides.


Solve for x to get:

-3x+9y =18
add 3x to each side
9y = 3x+18
divide by 9
y = 3/9 x +18/9
y = 1/3 x+2
the slope is 1/3
the y intercept is 2
-3x+9y =18
let y=0 to find the x intercept
-3x=18
divide by -3
x=-6
the x intercept is -6
P = m+n/q
by timesing by p then dividing by q
33.2522. If you take your calculator and type in 31.37 times 1.06 you'll get the answer very easily. This works because you're multiplying 31.37 by .06 but you're also keeping the 31.37.
