we are given

x^2+y^2-2x-4y-z+5=0

standard form:

We will complete x , y and z square

make all x , y and z terms together  

x^2-2x+y^2-4y-z+5=0

x^2-2x+y^2-4y-z=-5

x^2-2*1*x+y^2-2*2*y-z=-5

x^2-2*1*x+1^2+y^2-2*2*y+2^2-z=-5+1^2+2^2

(x-1)^2+(y-2)^2-z=0

z=(x-1)^2+(y-2)^2

surface:

It is an infinite paraboloid

Answer the question below please
PSYCHO15rus [73]

Answer:

x=7

Step-by-step explanation:

AC=3x+3  AB=-1+2x and BC=11

AC = AB + BC

ALL THE STEPS:

3 X + 3 = - 1 + 2 X + 11

3 X + 3 = 2 X + 10

3 X + ( - 2 X ) + 3 = 2 X + ( - 2 X ) + 10

X + 3 = 10

X + 3 + ( - 3 ) = 10 + ( - 3 )

X = 7
