maw [93]
3 dozen= 36, you need 720.
720/36= 20.
This means you'll need to scale up the recipe to a factor of 20. In other words, you'll need to multiple the amount of each ingredient required by 20 in order to have enough cookies for 360 people to each have two.

A rectangle has a height of 3n^2 and a width of 4n^2-5n-1.
Galina-37 [17]

Answer:

A = 12n^4-15n^3-3n^2

Step-by-step explanation:

The dimensions of a rectangle are length and breadth/width

Here we are given height . Assuming it to be one of the side of the rectangle , we will do the further calculation

Hence one side is

side 1 = 3n^2

And the other side is

Side 2 = 4n^2-5n-1

The area of rectangle = side 1 x side 2

A=3n^2 \times (4n^2-5n-1)

A=3n^2 \times 4n^2-3n^2 \times 5n-3n^2 \times 1

A=3 \times 4 \times n^2 \times n^2- 3 \times 5 \times n^2 \times n - 3n^2

A = 12n^4-15n^3-3n^2

Hence area can be given as expression

A = 12n^4-15n^3-3n^2
