The prime factorization of 240 is 2^{4} . 3 . 5 ⇒ last answer

Step-by-step explanation:

Prime number is the number that has only 2 factors 1 and itself

{2 , 3 , 5 , 7 , 11 , 13 , 17 , 19 , 23 , 29 , ............}

In prime factorization we use only the prime numbers

Ex: The factors of 15 are 1 , 3 , 5 , 15,

      Then the prime factors of 15 are 3 and 5 only because they are

       prime numbers

So to find the prime factors of a number do that

1. Factorize the number by divide it using prime numbers only

2. Write the number as a product of its prime factors

∵ 240 divisible by first prime number 2

∴ 240 ÷ 2 = 120

∵ 120 ÷ 2 = 60

∵ 60 ÷ 2 = 30

∵ 30 ÷ 2 = 15

- We divided the number by 2 for 4 times

∴ 2^{4} is a prime factor of 240

∵ 15 is divisible by prime number 3

∴ 15 ÷ 3 = 5

∴ 3 is a prime factor of 240

∵ 5 is divisible by prime number 5

∴ 5 ÷ 5 = 1

∴ 5 is a prime factor of 240

∴ The prime factors of 240 are 2^{4} , 3 , 5

The prime factorization of 240 is 2^{4} . 3 . 5

Margot is sewing a ribbon on a seam along the perimeter of a square pillow. The side length of the pillow is 2x2 1 inches. She p
Sauron [17]

The expression used for the length of ribbon that she needs for both pillows will be 4(2x^{2} +4x-6).

The total length of the pillow she needs will be  130 inches.

Given,

The side length of pillow is (2x^2 + 1) \ inches.

The side length of another pillow is 4x-7 \ inches.

We know that perimeter of square will be,

P=4\times length

So the perimeter of pillow will be,

P=4\times (2x^2+1)\\

P=8x^{2} +4

Similarly, the perimeter of another pillow will be,

P=4\times (4x-7)]

P=16x-28

Hence,the total length of ribbon that she needs for both the pillows will be,

8x^{2} +4+16x-28\\8x^{2} +16x-24\\4(2x^{2} +4x-6)

If x=3.5\\ then the total length of ribbon will be,

4(2\times 3.5^{2}+4\times 3.5-6)\\4(2\times 12.25+14-6)\\

4(24.5+8)

4\times 32.5\\

130 \ inches.

Thus the required expression will be 4(2x^{2} +4x-6) and the total length of ribbon she needs will be 130 inches.

So, the correct option will be (D).

Question: 69 = 9r -3<br> r =
In-s [12.5K]

Answer:

8 = r

Step-by-step explanation:

69 = 9r -3

Add 3 to each side

69+3 = 9r -3+3

72 = 9r

Divide each side by 9

72 / 9 = 9r/9

8 = r
