Answer:

Step-by-step explanation:

You have:

x^2+y^2-8x+27=0

Since the variable 'x' appears twice, I am going to choose to group together the terms as to create a 2nd degree trinomial:

(x^2-8x+27)+y^2=0

This allows us to complete the square and factor the trinomial:

(x^2-8x+16-16+27)+y^2=0

(x^2-8x+16)+11+y^2=0

(x-4)^2+y^2+11=0

(x-4)^2+(y-0)^2=-11

This is not a valid circle equation in the real plane. It has a complex radius of:

r=i\sqrt{11}

And is centered at the point:

(4,0)

Please answer this correctly without making mistakes
Monica [59]

Answer:

g=56

Step-by-step explanation:

In similar shapes, corresponding sides are always in the same ratio.

For example,

if the sides in triangle 1 were a and b, and triangle 2 had side lengths c and d, c and a had the same ratios, and b and d had the same ratios

and triangle 1 was similar to triangle 2, the ratio between the sides of the triangles would be

a/c, which is also equal to b/d

What that means is that in this situation, 8/5=g/35.

8/5=g/35

Cross multiply.

(8)*(35)=g*(5)

280=5g

g=56
