Formula for perimeter of rectangle:
P=2(L+w)
P=2L+2w
Here Perimeter, p= 72 ft
And scale factor of length and width=3.5 which means rectangle is enlarged.
So perimeter of rectangle= 3.5 x 72
P=252ft 

Answer: 252 ft

We know the perimeter of the original rectangle is 72ft.
We also know that the perimeter P of the rectangle is defined as:
P=2L+2W.
So P is directly proportional to L+W. This means that if L or W were to get bigger, P will get bigger, and if L or W were to get smaller P will get smaller.

The question also states that both L and W are scaled by the same factor of 3.5 .
This means the sum of the dimensions L+W is scaled by 3.5
It also means that the perimeter is upscaled by 3.5 as it is proportional to L+W.
P = 72 ft × 3.5 = 252 ft.

252 ft is the answer.

Juan always saves the same amount from his weekly allowance. The table shows how much he has saved at different times.
erastova [34]
On the 14 week Juan will save $ 52 because each 3 week he earns 3.
So you do 9 divide by 3 and get 3. Then you do 3 times 2 and get 6.
46 + 6 = 52

Give an example of: degree of a polynomial is the highest sum of one of its terms, explain.
yuradex [85]

Example 1  Perform the indicated operation for each of the following.

<span>(a) </span>Add  to 

<span>(b) </span>Subtract   

Solution

(a) Add  to .

The first thing that we should do is actually write down the operation that we are being asked to do.

                                          

In this case the parenthesis are not required since we are adding the two polynomials.  They are there simply to make clear the operation that we are performing.  To add two polynomials all that we do is combine like terms.  This means that for each term with the same exponent we will add or subtract the coefficient of that term.

 

In this case this is,

           

[Return to Problems]

 

(b) Subtract  from .

Again, let’s write down the operation we are doing here.  We will also need to be very careful with the order that we write things down in.  Here is the operation

Can someone please help me on this??
Usimov [2.4K]

Answer:

C

Step-by-step explanation:

To solve this use the equation x^2 -15x - 50 = y given in the problem and the value y = 50. Substitute y = 50 then solve for x by factoring.

x^2 -15x - 50 = 50\\x^2 - 15x -100 = 0

Find two numbers which multiply to -100 and also add to -15. The numbers are -20 and 5.

So the factored form is (x-20)(x+5) = 0.

Set each factor equal to 0 and solve.

(x-20) = 0 so x = 20.

(x+5)=0 so x = -5.

This means the temperature is 20 degrees C or -5 degrees C. Only 20 is an option. The solutions is C.
