Answer:

Part A:  12 < 4x < 24  (OR  3 < x < 6)

Part B: the length x needs to be bigger than 3 ft but smaller than 6 ft

Part C: Because the area must be more than 12 square feet and the width is 4 feet, the length must be greater than 3 feet.

Step-by-step explanation:

<u>Part A</u>

  • Area of rectangle = width x length

We are told that the width = 4 ft

Let x = length

Therefore, area = 4x

The area needs to be more than 12 ft² but less than 24 ft²

Therefore, 12 < 4x < 24

<u>Part B</u>

12 < 4x < 24

Divide everything by 4:  3 < x < 6

So the length x needs to be bigger than 3 ft but smaller than 6 ft

<u>Part C</u>

Because the area must be more than 12 square feet and the width is 4 feet, the length must be greater than 3 feet.

yuri has a rope 12 meters long. he cuts it into pieces that are each 2 meters long. what fraction of the rope is one piece
Lelu [443]
So the numerator of your fraction (the top number) is the amount that was cut. The denominator (the bottom number) is the total amount of rope. So, your fraction would be 2/12. You can still simplify that by dividing both the numerator and denominator by 2 and end up with 1/6. Does that make sense? If you need any more help, go ahead and message me :)
