I think a) would be the answer. I proceeded by elimination: the domaine of the function goes from 3 and continues to infinity, so that leaves with a) and b) as possible answers. Both have the same range and both of their functions reflect over the x axis, so we have to compare the two answer by looking at the position of the function in the graph. The function is in the first quadrant (top right corner), so the position of the function has to be at our right, which leads us to a).

If the area of Bianca’s rectangular backyard patio is represented by the expression x2 – 18x + 81, and the length of the patio i

Verizon [17]

<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 !

L 1.1.5 Quiz: Scale Drawings Question 1 of 5 What is the area of the real object that the scale drawing models? Scale factor: 1.

8090 [49]

Answer:

18 cm²

Step-by-step explanation:

Based on the given information, the first object has an area of 12 cm² and the scale factor is 1.5. Since we know that, we can simply take the first area and multiply it by the scale factor:

12 · 1.5 = 18

Therefore, the second object will have an area of 18 cm².
