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 !

IceJOKER [234]

If there were two electricians, they'd need to install 48 fixtures per person.. if it takes 20 minutes for each fixture, it would take a total of 960 minutes, which converts to 16 hours. If a work day was only 8 hours, it would take two electricians TWO work days to install 96 light fixtures, or 24 light fixtures for four floors.
