What is the value of x ?
Ivan

Answer:

x = 3

Step-by-step explanation:

Given two secants drawn from an external point to the circle, then

The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is

x(x + 21) = (x + 1)(x + 1 + 14)

x² + 21x = (x + 1)(x + 15) ← expand using FOIL

x² + 21x = x² + 16x + 15 ( subtract x² + 16x from both sides )

5x = 15 ( divide both sides by 5 )

x = 3

Consider the equation below. X2 + y2 − 2x − 4y − z + 5 = 0 reduce the equation to one of the standard forms. Classify the surfac
jeka57 [31]

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
