Please find the attached file for a better understanding of the explanation given here.
the attached diagram is a generated image of the first fifteen rows of a pascal's triangle. As can be seen from the image, the least four-digit number in the first fifteen rows of pascal's triangle is 1001.
In the diagram attached that number is present in the very last row and is highlighted using a yellow rectangle.
Answer:
Equation:
or 
Solution:
Step-by-step explanation:
The formula that is used to calculate the perimeter of a square is:

Where "s" is the side lenght the square.
Knowing that Xin used 20 yards of fencing to build the walls of a square chicken coop (in which the lenght in yards of each wall is represented with "x"), you can identify that:

Then, you can susbtitute values into the formula
:
Finally, you must solve for "x" in order to find its value.
This is:

Answer:
The value of y is 50.
Step-by-step explanation:
It is 50 because it is the exact same as the first degree.
And at least give a picture of problem please so we can solve it easily!! hope you next time!!
Answer:
10 miles
Step-by-step explanation:
3+1x=13
Minus 3 from both sides.
3-3+1x=13-3
1x=10
Then divide both sides by 1.
1x/1=10/1
x=10
