Nady [450]

Answer:

  • 14 ft and 30 ft

Step-by-step explanation:

<u>Perimeter is</u>

<em>P = 2(l+w), where l= length, w = width</em>

  • P = 88
  • l = w + 16

<u>Substitute values to find the value of w:</u>

  • 88 = 2(w + 16 + w)
  • 2w + 16 = 44
  • 2w = 28
  • w = 14

Then

  • l = 14 + 16 = 30

Dimensions are 14 ft and 30 ft

What is a common ratio
Umnica [9.8K]

A definition of a  common ration Is the number multiplied must be the same for each term in the sequence. The common ratio is the amount between each number in a geometric sequence. To determine the common ration you can just divide each number from the number preceding it in the sequence. Here is an example I found of a common ration to further help you

2,4,8,16

16/8=2 you would then continue to divide to ensure that the pattern is the same for each number

8/4=2

4/2=2 the ratio is the same for each one so the common ration would be 2 I hope this helps could I please get a brainliest :)

sesenic [268]

Answer: 1346cm

Step-by-step explanation:

From the question, we are informed that Reagan has a rectangular bedspread that measures 238 centimeters by 435 centimeters and that he wants to sew a fringe around the edge of the bedspread.

This simply means that we have to find the perimeter of the rectangular bedspread and this will be:

= 2(length + width)

= 2(435 + 238

= 2(673)

= 1346cm

The length of fridge needed by Reegan is 1346cm.
