the length of a rectangle is 3 inches greater than the width. write a polynomial that represents the area of the rectangle

Answers

Answer 1
Answer:

The polynomial that represents the area of the rectangle is \rm W^2+3W.

Given

The length of a rectangle is 3 inches greater than the width.

Area of the rectangle;

The area of the rectangle is given by the product of the length and width.

The area of the rectangle is given by;

\rm Are \ of \ the \ rectangle=Length * width

Let, the length of the rectangle be L and the width of the rectangle is W.

The length of a rectangle is 3 inches greater than the width.

L = W + 3

Therefore,

The polynomial that represents the area of the rectangle is;

\rm Are \ of \ the \ rectangle=Length * width\n\n\rm Are \ of \ the \ rectangle=W * (W+3)\n\n\rm Are \ of \ the \ rectangle=W^2+3W

Hence, the polynomial that represents the area of the rectangle is \rm W^2+3W.

Answer 2
Answer:

Answer:

Length of a rectangle is 3 inches greater than the width, so:

L = W + 3

Area of a rectangle:

A = L x W

A = ( W + 3 ) x W

A = W2 + 3 W ----------------- Polynomial representing area of the rectangle in terms of Width.

Substitute W = 4 to find the area of the rectangle.

A = 42 + 3 (4)

A = 16 + 12

A = 28 inch2

L = W + 3

L = 4 + 3

L = 7 inches

24 is what percent of 60

Answers

Work is provided in the image attached.
100%/x%=24/60.
(100/x)*x=(24/60)*x - we multiply both sides of the equation by x.
100=0.4*x - we divide both sides of the equation by (0.4) to get x. 

hope this helps you understand.
best i could do.

1. c + 3/10 = 31/70
2. w + 6 1/2 = 10 1/6

Answers

Answer:

1. c = 1/7

2. w = 11/3

Step-by-step explanation:

1. c + 3/10 = 31/70

move 3/10 to the opposite to get c, we can do this by subtracting 3/10 from both sides

c = 31/70 - 3/10

c = 1/7

2. w + 6 1/2 = 10 1/6

same thing, move 6 1/2 by subtracting it from both sides

w = 10 1/6 - 6 1/2

w = 11/3

1. C=1/7
Work:
You have to subtract 3/10 on both sides.
2. -4/3
You have to subtract 6 1/2 on both sides.
