1, the answer should be 40, it is about 28 miles so that is closest to 40
2, this is (6,3) or c
For the square with side length n, the diagonal measures:

<h3>
How to get the length of the diagonal?</h3>
The sidelength of the square is n, and we want to get the length of the diagonal d.
Notice that the diagonal is the hypotenuse of a right triangle whose catheti measure n.
Then we can use the Pythagorean theorem, which says that the square of the hypotenuse is equal to the sum of the squares of the cathetus;

That is the length of the diagonal.

Answer:
The aspect of the lines that are the same is that they have the same slope while the aspect of the lines that are different is that they have different x and y-intercepts
Parallel lines are lines that do not meet in a xy-plane
If the parallel lines are vertical lines, they will both cut the x-axis at different points showing that they will have different x-intercept.
Similarly, if the parallel lines are horizontal lines, they will both cut the y-axis at different points showing that they will have different y-intercept.
Parallel lines are also known to have the same slope. This is the aspect that is common to both lines.
Step-by-step explanation:
number a is too low so we will work with c after all I put that and got it eight
