The area of a rectangular pool is (14x^2+21x) square feet. If it is 7x feet long, what is the width, in feet?

Answers

Answer 1
Answer: (14x^2+21x) = 7x(2x + 3)

A= L * W

but L = 7x so W = 
2x + 3

answer: 
width is (2x +3) feet

Answer 2
Answer:

Answer:

you get (2x+3), because 14 divided by 7 = 2 and 21 divided by 7 = 3

Answer:

x=7

Step-by-step explanation:

t(x) = 7x, t(x) = 49

Due to the transitive property, you can say that

7x=49

divide both sides by 7

x=7

A rectangular garden has a perimeter of 578 yds.The length is one more than three times the width.
Find the dimensions of the garden.

Answers

Answer:

Width (w) = 72 yds

Length (L) = 217 yds

Step-by-step explanation:

Let L represent the length.

Let w represent the width.

From the question given above:

Perimeter (P) = 578 yds.

Length (L) is one more than three times the width (w). This can be written as. Follow:

three times the width (w) = 3w

Therefore, the length (L) is given by:

L = 1 + 3w

Next, we shall determine the value of length (L) and width (w). This can be obtained as follow:

Recall:

Perimeter of rectangle is given by:

P = 2(L + w)

P = 2L + 2w

Perimeter (P) = 578 yds.

Length (L) = 1 + 3w

Width (w) = w

P = 2L + 2w

578 = 2(1 + 3w) + 2w

Clear bracket

578 = 2 + 6w + 2w

578 = 2 + 8w

Collect like terms

578 - 2 = 8w

576 = 8w

Divide both side by 8

w = 576/8

w = 72

Therefore, the width is 72 yds

L = 1 + 3w

w = 72

L = 1 + 3(72)

L = 1 + 216

L = 217

Therefore, the length is 217 yds.

The dimensions of the garden is given below:

Width (w) = 72 yds.

Length (L) = 217 yds.

I'm going to say a arithmetic sequence

Step-by-step explanation:

I say this because a arithmetic sequence of numbers such that the difference between the consecutive terms is constant. Difference here means the second minus the first. For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with common difference of 2. So, when Nya sent the letter to 4 friends, her friends copied and sent it to four other friends. So, the sequence would be (if it continues) 4, 8, 12, 16, 18, etc.

A dime weighs 50% as much as a nickel does what is the weight of a dime?

Answers

It's weight would be: x*150 / 100

Where, x= weight of nickel

Final answer:

A nickel weighs 5 grams. As a dime is said to weigh 50% as much as a nickel, we calculate 50% of 5 to find the weight of the dime, which gives us 2.5 grams.

Explanation:

The subject of this question is in the context of Mathematics, more specifically proportional relationships. The weight of a nickel is 5 grams. As mentioned, a dime weighs 50% less than a nickel. So to find the weight of the dime, we calculate 50% of 5 grams.

First, to find 50%, we need to divide by 100 and then multiply by 50. That is: (5 / 100) * 50 = 2.5 .

So, a dime weighs 2.5 grams. Always remember, weight measurements can have slight variations depending upon measurement techniques and tools used. For instance, if you place a coin on a standard electronic balance, you may obtain a weight of 2.5 g with a nominal uncertainty in the measurement of ± 0.01 gram. However, in a general sense for our calculation with given data, the weight of a dime is indeed 2.5 grams.
