What is x squared minus 4x minus 45

Mathematics
1 answer:
Mazyrski [523]3 years ago
3 0

That's a second-degree expression in 'x'.  It represents a number,
but the number it represents completely depends on the value of 'x'. 
And if the value of 'x' ever changes, then the value of the whole
expression instantly changes.

The expression is also the product of   (x + 5)  and  (x - 9) .

Darina [25.2K]

Answer:

The answer to your question is letter C

Step-by-step explanation:

From the graph, we get the center and the radius

- The center is the point shown in the graph and its coordinates are (2, -1).

- The length of the radius is 4 units, from the center we count horizontally the number of squares (4)

Substitution

                    (x - 2)² + (y + 1)² = 4²

or                 (x - 2)² + (y + 1)² = 16
