A rectangle's length is three times its width. Let w denote the rectangle's width. What polynomial represents the rectangle's ar
Ket [755]
<span>A = l x w
Since 
l = 3w

Substitute the l with 3w
The formula will be

A = 3w + w
A = 4w

An example:
The given known values are: Length of 4 cm Width is unknown Perimeter is 34 cm Find the dimensions of the rectangle.   Since the geometric formula for perimeter is: </span>
P= 2 (l + w) 
L = 2w – 4 cm 
W =?   
Derivation and solution: 
34 = 2 (2w - 4) + 2w <span>
34 =  4w – 8 + 2w</span> 
42 = 6w 42/6 = w 
W = 7 cm   

34 = 2l + 2(7) 
34 = 2l + 14 
2l = 34 – 14 
2l = 20 
L = 20/2 
L = 10 cm<span> <span>

How do you distinguish between multiples and factors of a number, and justify your evaluation of the LCM &amp; GCF of a set of n
Reil [10]

Answer:

Look to the explanation

Step-by-step explanation:

- <u><em>Multiples of a number</em></u> are the numbers after multiplying the number

  by an integer

- Ex: The multiples of 2 are 2 , 4 , 6 , 8 , .......... because 2 × 1 = 2 ,

  2 × 4 = 4 , 2 × 3 = 6 and 2 × 4 = 8

- <u><em>Factors of a number</em></u> are the number multiplied together to get the

  number

- Ex: The factors of 6 are 1 , 2 , 3 , 6 because 1 × 6 = 6 and 2 × 3 = 6

- <u><em>Lowest common multiple of the set of numbers (LCM)</em></u> is the

  smallest number divisible by these numbers

- Ex: The lowest common multiple of 2 and 3 is 6 because 6 is divisible

  by 2 and 3 and there is no number before it divisible by both

- <u><em>Greatest common factor of the set of numbers (GCF)</em></u> is the highest

  common factor of these numbers

- Ex: The greatest common factor of 12 and 18 is 6 because

→ The factors of 12 are 1 , 2 , 3, 4, 6, 12

→ The factors of 18 are 1 , 2 , 3 , 6 , 9 , 18

→ The greatest common factor on both numbers is 6
