lenght :

2x - 3

breadth :

4x + 5

AREA = LENGTH × BREADTH

= (2x - 3) \times (4x + 5)

multiplying the above gives :

= 8 {x}^{2}  + 10x - 12x - 15

= 8 {x}^{2}  - 2x - 15

A line segment is defined by which of the following statements?
kaheart [24]

The only given option that correctly defines a line segment is;

<u><em>Option C; All points between and including two given points.</em></u>

      In geometry in mathematics, a line segment is defined as a part of a line that is bounded by two distinct end points.

Now, let us look at the options;

Option A; This is not correct because a line segment must have 2 distinct endpoints

Option B; This is not correct because a line segment is a part of a line and not a set of points.

Option C; This is correct because it tallies with our definition of line segment.

Option D; This is not correct because a line segment does not extend infinitely.
