As far as the old dimensions of the photo are concerned,
Width of the photo = 3"
Length of the photo = 5"
New length of the photo = 7 inches
Let us assume the new width of the photo = x inches
Then
3/5 = x/7
5x = 7 * 3
5x = 21
x = 21/5
   = 4.20 inches
So the correct option among all the options that are given in the question is the first option. I hope that the answer has come to your help.
        
             
        
        
        
600 ft. This is because you travel 10 feet per second and there are 60 seconds in a minute. 10 x 60 =600

Given:
 is subtracted from 3.
 is subtracted from 3.
To find:
The result of the given statement in the standard form of the polynomial.
Solution:
We need to find the result when  is subtracted from 3.
 is subtracted from 3.
So, the resulted polynomial can be written as:

On simplification, we get
 
               ![[\because (a+b)^2=a^2+2ab+b^2]](https://tex.z-dn.net/?f=%5B%5Cbecause%20%28a%2Bb%29%5E2%3Da%5E2%2B2ab%2Bb%5E2%5D)
 
 
 
 
 
 
Therefore, the resulted polynomial in standard form is  .
