Use the information given to answer the question. Consider the rectangle.

Part A

If the area of the rectangle is represented by the expression

(

x

−

3

)

(

x

+

3

)

square units, which expression represents an equivalent area?

(

x

2

−

9

)

square units

( x 2 − − 9 ) square units

(

x

2

−

6

x

+

9

)

square units

( x 2 − − 6 x + 9 ) square units

(

x

2

+

6

x

−

9

)

square units

( x 2 + 6 x − − 9 ) square units

(

x

2

+

9

)

square units

Area is (x² - 9) units squared.

Step-by-step explanation:

• from difference of squares quadratic property:

→ a is x

→ b is 3

• Therefore:

the answer is a

step-by-step explanation:

because if you put 1 in to the square root of x it equals 300.

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
