The function f x =x2 +3x-10 models the area of a rectangle. a: describe the length and width of the rectangle in terms of x b: what is a rectangle in terms of x

A .

B. domain of here is all values of x > 2 .

Step-by-step explanation:

Correct question is : the function models the area of a rectangle. a: describe the length and width of the rectangle in terms of x b: what is a domain for above function in relation to rectangle . Let's solve:

a: describe the length and width of the rectangle in terms of x

Let's factorise :

⇒

⇒

⇒

Since , ⇒ So

.

b: what is a domain for above function in relation to rectangle

Since area is always > 0 , and (length , breadth)>0 So,

⇒ Therefore, domain of here is all values of x > 2 .

in full, on time, every time

Step-by-step explanation:

in full, on time, every time because even if little is left out it would again a large amount together with the interest. Also as the limit is low it can easily be reimbursed
