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 !
You are looking at around 81.5% i assume by shifting the standard deviation by the same amount on both sides the % will not change
i split the normal distribution curve into 8 pieces
.15 +2.35+13.5+34+34+13.5+2.35+.15 34+34+13.5=81.5%
the ones bolded are the sections that u r dealing with
now the standard deviation is only 4400 so these numbers are going to be skewed off to the right a bit however bcus both sides are skewed evenly i believe they balance each other out
im not completely certain of this but still i hope i helped if so give me a brainliest answer i need a few more to move up a rank -J (:
