Answer:
The correct answer is 25
Step-by-step explanation:
It is given a quadratic equation,
x² – 8x = 9
<u>To find the number to be added</u>
The given equation be x² – 8x = 9
here we have to add (b/2)² - the square of half the coefficient of x,
Here b = -8
(b/2)² = (-8/2)² = -4² = 16
Add both side with 16
x² – 8x + 16 = 9 + 16
(x - 4)² = 25
(x - 4)² = 5²
Solids or three-dimensional forms are shapes or figures that have three (or more) dimensions. The solid could be a Triangular prism or a pyramid.
<h3>What is a solid?</h3>
Solids or three-dimensional forms are shapes or figures that have three (or more) dimensions. Solid Geometry is the study of the characteristics, volume, and surface area of three-dimensional forms.
Given a solid is cut by a plane that is perpendicular to its base, forming a two-dimensional cross-section in the shape of a triangle. Therefore, the solid could be a Triangular prism or a pyramid.

Answer:
Center
Minor segment.
Step-by-step explanation:
See the attached diagram of the circle.
Here, two blanks are there and we have to fill up with the correct circle vocabulary.
The blank with an arrow can be filled up by the Center of the circle about which the circle is drawn.
And the other blank should be the Minor segment of the circle.
A chord divides the circle into two areas, major and minor segments. (Answer)
