Step-by-step explanation:
number x = 9.688888 is a rational number. This is because when you take x = 9.6888 and multiply 10 from x 10x = 96.888. So on and so forth.
Yes
The new square has length: 10 + l, where l is the original length of the square, and it's area is (10 + l)^2;
So, we solve the equation: 3 x l^2 = (10 + l)^2;
Then, 3 x l^2 = 100 + 20 x l + l^2;
Finally, 2xl^2 - 20xl - 100 = 0; / ÷2;
l^2 - 10l - 50 = 0 (we use the quadratic equation formula);
The only positive solution is l = 5(1+ \sqrt{3} );

Answer:
25 feet
Step-by-step explanation:
Rectangle has a length (given as 20 feet) and a width (given as 15 feet).
Also, the diagonal is the length of the side from one corner to opposite corner. THis is what we need to find. According to Pythagorean THeorem:
Length^2 + Width^2 = Diagonal^2
We know:
Length = 20
Width = 15
Now, we find the diagonal:
Hence, the diagonal (length of path that extends from one corner to the opposite corner) has a length of 25 feet.
