Verizon [17]

1) $width=x-9$

2) Rectangular shape is square shape patio !

Step-by-step explanation:

Here we have , the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio is represented by the expression x − 9: We need to find

1. what is the expression for the width of the patio? Explain and show all work.

We know that area of rectangle = $Length(width)$

⇒ $x^2-18x+81=(x-9)(width)$

Factorizing RHS:

⇒ $x^2-9x-9x+81=(x-9)(width)$

⇒ $x(x-9)-9(x-9)=(x-9)(width)$

⇒ $(x-9)(x-9)=(x-9)(width)$

⇒ $width=x-9$

2. what special rectangular shape is the patio?

Now , we see that

$Length = x-9\\Width=x-9$

A rectangle whose length & width are equal is known as a square ! Hence , Rectangular shape is square shape patio !

Does the equation x2 - 6x + y2 - 6y = -9 intersect the y-axis? A) Yes, it intersects the y-axis at (0, 3). B) Yes, it intersects

Dimas [21]

Answer:

The answer to your question is letter A

Step-by-step explanation:

Data

x² - 6x + y² - 6y = -9

Process

1.- Find the center

x² - 6x + ( )² + y² - 6y + ( )² = -9

x² - 6x + (3)² + y² - 6y + (3)² = -9 + 9 + 9

(x - 3)² + (y - 3)² = 9

Center = (3, 3)

radius = 3

See the graph below

2.- From the previous information and the graph, we conclude that the equation intercepts the y-axis in (0,3)
