2) Rectangular shape is square shape patio !
<u>Step-by-step explanation:</u>
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 = 
⇒ 
Factorizing RHS:
⇒ 
⇒ 
⇒ 
⇒
2. what special rectangular shape is the patio?
Now , we see that
A rectangle whose length & width are equal is known as a square ! Hence , Rectangular shape is square shape patio !
The number terms in the given expression is 3, they are 5xy, -3x and -82.
The given expression is 5xy-3x-82.
<h3>What is an expression?</h3>
An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
The terms involved in an expression in math are:
