The length of a rectangle is 3 centimeters less than five times its width. Its area is 14 square centimeters. Find the dimensions of the rectangle.
Find the Width and the Length
W=
L=

Answers

Answer:

The length of rectangle is 7 cm and width is 2 cm.

Step-by-step explanation:

Given that:

Area of rectangle = 14 square centimeters

The length of a rectangle is 3 centimeters less than five times its width.

Let,

L be the length and W be the width of the rectangle.

L = 5W - 3

Area of rectangle = Length * Width

14 = (5W-3)*W

[tex]14=5W^2-3W\\5W^2-3W-14=0[/tex]

Factorizing the equation;

[tex]5W^2-10W+7W-14=0\\5W(W-2)+7(W-2)=0\\(5W+7)(W-2)=0[/tex]

Either,

5W+7 = 0

5W = -7

W = -7/5

Or,

W-2 = 0

W=2

As width of rectangle cannot be negative, therefore,

Width = 2 centimeters

Length = 5(2) -3 = 10-3 = 7

Hence,

The length of rectangle is 7 cm and width is 2 cm.

What is the value of x?

Answers

Answer:

x = 16

Step-by-step explanation:

(x+2) + (7x+2) + (3x) = 180

Add like terms

7x + x + 3x = 11x

2 + 2 = 4

11x + 4 = 180

Subtract 4

11x + 4 = 180

11x = 176

Divide by 11

11x = 176

x = 16

Step-by-step explanation:

Hi,

The ratio of two numbers is 3 to 5.

Let x represent the constant of the proportionality

3x + 5x = 136

8x = 136 (divide both sides by 8)

x = 17

The numbers are:

3*17 = 51 and

5*17 = 85

CHECKING our answer***

51 + 85 = 136

Answer:

51 and 85

Step-by-step explanation:

add the two ratio parts (3 & 5) and divide by total. you get 17. then multiply the parts by 3 and 5 to get the answer
