the length of marshalls retangular poster is 2 times the width if the perimeter is 24 inches what is the area
Ilia_Sergeevich [38]
Let us assume the width of the rectangle = x
Then
The length of the rectangle = 2x
The perimeter of the rectangle = 24 inches
We know the formula of the perimeter of a rectangle is
Perimeter = 2 (length + Breadth)
24 = 2 (2x + x)
24 = 2 * 3x
24 = 6x
x = 24/6
   = 4
So the width of the rectangle = 4 inches
length of the rectangle = 2x
                                     = 2 * 4 inches
                                     = 8 inches
Now 
The Area of the rectangle = Width * Length
                                          = 4 * 8 inches^2
                                          = 32 inches ^2
So the area of the rectangle is 32 square inches. I hope i have helped you.

Given data

Last years shipment= 37220  lamps

These years shipment= 29776 lamps

% Decrease= Initial-Final/Initial*100

% Decrease= 37220-29776/29776*100

% Decrease= 0.25*100

% Decrease= 25%

Hence the decrease is 25%

Find the x-intercept and y-intercept of the line. 7x+5y=-15
riadik2000 [5.3K]

Answer:

The x-intercept is (-2 1/7, 0).

The y-intercept is (0, -3).

Step-by-step explanation:

To find the y-intercept, substitute x with zero.

To find the x-intercept, substitute y with zero.

Finding the y-intercept by substituting x with zero:

7*0 + 5y = -15

5y = -15

y = -3

The y-intercept is (0, -3).

Finding the x-intercept by substituting y with zero:

7x + 5*0 = -15

7x = -15

x = -15/7

x = -2 1/7

The x-intercept is (-2 1/7, 0).
