Which term describes the number of square units contained in the interior of
a polygon?
A. Perimeter
B. Width
C. Height
D. Area

Area describes the number of square units contained in the interior of  a polygon.

Option D.

Explanation:

Area is the amount that communicates the degree of a two-dimensional figure or shape or planar lamina, in the plane. Surface zone is its simple on the two-dimensional surface of a three-dimensional article. The area of a figure is the number of squares required to cover it completely, like tiles on a floor.

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

x=half

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3
