Answer:

<h2>x2−10 because the area expression can be rewritten as (x2−10)(x2+10) which equals (x2−10)((x2−10)+20).</h2>

Step-by-step explanation:

The area of the rectangle is x^{4} -100, which can be factored as (x^{2} +10)(x^{2} -10), because it's the difference of two perfect squares.

But, we know that l=20+w, where l is the length and w is the width.

Additionally, l=x^{2} -10+20 and w=x^{2} -10, which means l=x^{2} +10.

Therefore, the right answer is A.

Answer:

1. x^2-10 because the area expression can be rewritten as (x^2-10)(x^2+10)which equals (x^2-10)((x^2-10)+20).

Step-by-step explanation:

Area of the rectangle =(x^4-100)

x^4-100=(x^2)^2-10^2\\$Applying difference of two squares: a^2-b^2=(a-b)(a+b)\\(x^2)^2-10^2=(x^2-10)(x^2+10)

Since the length of a rectangle is 20 units more than its width.

Width: x^2-10\\Length=x^2+10=x^2-10+20

The correct option is therefore 1.

The following function represents the value of a house after x years: f(x) = 242,000(0.96)x What does 0.96 represent?
9966 [12]

Because the 0.96 is less than 1, it means that the house loses value over the years.

Convert 0.96 to a percent: 0.96 = 96%

100% - 96% = 4%

The house loses 4% of it's value every year.
