Part A. At the local baker you can get 10 cookies for $2. How many cookies could you get for $5 dollars?
Yakvenalex [24]

Answer:

Pt. A: 25 cookies. Pt. B. $10.00

Step-by-step explanation:

1st you need to divide 10 cookies and $2 dollars, so 10/2= 5 cookies. So, it would be 5 cookies per dollar. So, then you would multiply 5 cookies*5 dollars, that equals 25. you would get 25 cookies for $5.00.  

So, for Part B, you would divide 50 cookies by $5 dollars, and that would equal $10.00.

Hope this helped you!!! (:

Which function models the area of a rectangle with side lengths of 2x - 4 units and x + 1 units?
aalyn [17]

Answer:

Area of rectangle, f(x)=2x^2-2x-4.

Step-by-step explanation:

We are given with side lengths of a rectangle are (2x-4) units and (x+1) units. It is required to find the area of rectangle.

The area of a rectangle is equal to the product of its length and breadth. It is given by :

A=L\times B

Let us consider, L = (2x-4) units and B = (x+1) units

Plugging the side lengths in above formula:

A=(2x-4)\times (x+1)

A=2x^2+2x-4x-4\\\\A=2x^2-2x-4

So, the function that models the area of a rectangle is f(x)=2x^2-2x-4.
