A student was given the equation 2x^2+ 3x +7=0 to solve by completing the square. The first step that was written is shown below.
2x² + 3x=-7
The next step in the student's process was x² + x +c= - +c State the value of c that creates a
perfect square trinomial. Explain how the value of c is determined.

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

double number line is not a standard concept, so it must have been defined in your textbook. assume top line is numerator.
