Answer:

The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is (x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93.

Step-by-step explanation:

Any sphere centered at (h,k,s) in an Euclidean space with a radius r is represented by the following formula:

(x-h)^{2} +(y-k)^{2}+(z-s)^{2} =r^{2}

If (x,y,z) = (7,1,-3) and (h,k, s) = (5,6,5), the radius of the sphere is obtained:

(7-5)^{2}+(1-6)^{2}+(-3-5)^{2} = r^{2}

r^{2} = 93

r = \sqrt{93}

The equation of the sphere that passes through the point (7,1,-3) and center at (5, 6, 5) is (x-5)^{2}+(y-6)^{2}+(z-5)^{2} = 93.

Answer:

A. Correct choice is C

B. Correct choice is B

Step-by-step explanation:

4 times the number x is 4x.

The sum of 4 times the number x and 26 is 4x+26.

The sum of 4 times the number x and 26 is 130, then

4x+26=130.

Correct option is option C.

Solve this equation:

4x=130-26,

4x=104,

x=26.
