The length of a rectangle is 20 units more than its width. The area of the rectangle is x4−100.
Mice21 [21]

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 function c=180n+250 represents the total lodging cost c (in dollars) for a stay at a vacation destination of n nights.
Svetlanka [38]

Given:

The function for the total lodging cost c (in dollars) for a stay at a vacation destination of n nights is

c=180n+250

Budget = $900

To find:

The number of nights you can stay at you vacation destination.

Solution:

Since, budget is $900, therefore, the cost must be less than or equal to $900.

c\leq 900

180n+250\leq 900

180n\leq 900-250

180n\leq 650

Divide both sides by 180.

n\leq \dfrac{650}{180}

n\leq 3.611

Number of nights must be a whole number. So, greatest whole value of n is 3.

Therefore, you can stay 3 nights, i.e., n=3.
