<u>1) </u> $width=x-9$

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 = $Length(width)$

⇒ $x^2-18x+81=(x-9)(width)$

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 !

you sell 4,000 per week in bags of dog food at 30% margin. You sell 3,000 per week in dog food toys at 45% margin. Which generat

Alona [7]

Answer:

Margin on dog food toys is more than margin on bags of dog food.

Step-by-step explanation:

Given information:

Sale of bags of dog food = 4000 per week

Margin on bags of dog food = 30%

Total margin on bags of dog food is

$4000\times \frac{30}{100}=1200$

Sale of dog food toys = 3000 per week

Margin on dog food toys = 45%

Total margin on dog food toys is

$3000\times \frac{45}{100}=1350$

Since 1350 > 1200, therefore margin on dog food toys is more than margin on bags of dog food.
