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

What is 30% of 70. show your work<br>​
mamaluj [8]

Answer: 21

Step-by-step explanation:

we have two simple equations:

1) 70=100%

2) x=30%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

70/x=100%/30%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 30% of 70

70/x=100/30

(70/x)*x=(100/30)*x - we multiply both sides of the equation by

70=3.33333333333*x - we divide both sides of the equation by (3.33333333333) to get x

70/3.33333333333=x

The fore, the answer is 21
