Answer:
x= 14
Step-by-step explanation:
sqrt( x-5) = x-11
Square each side
(sqrt( x-5))^2 = (x-11)^2
x-5 = x^2 - 22x +121
Subtract (x-5) from each side
x-5-x+5 = x^2 -22x +121 -x+5
0 = x^2 -23x +126
Factor
0 = ( x-14) ( x-9)
Using the zero product property
x-14 = 0 x-9=0
x=14 x=9
Check the solutions
sqrt( x-5) = x-11
sqrt( 14-5) = 14-11
sqrt(9) = 3
3=3
solution
sqrt( x-5) = x-11
sqrt(9-5) = 9-11
sqrt(4) =-2
2 = -2

185% = 185/100
185/100 = 37/20
The simplest form fraction of 185% is 37/20.
Answer:
c
Step-by-step explanation:
Step-by-step explanation:
it is the vertex form.
remember, (h, k) is the vertex point.
the vertex being the point of the (quadratic) parabola, where the curve turns around.
depending on the orientation of the parabola (vertex up or vertex down) as defined by the sign of a, this is either the minimum or the maximum of the curve.
so, the first a. is correct.
and so is the second a., as they play an important role when completing the square and hence finishing the transformation.
I believe you use the 12 inches one
