x = All real numbers or 0.
First you should distribute both sides of the equation. This gives you 42x+42=42x+42.
Then, subtract 42 from both sides. This gives you 42x=42x.
Now, divide 42 on both sides. This gives you x=0 or all real numbers.
Answer: The required width of the park is 3 miles.
Step-by-step explanation: Given that a 5 mile jogging path diagonal divides a rectangular park in half and the park is 4 miles long.
We are to find the width of the park.
As shown in the attached figure below, the diagonal BD divides the rectangle ABCD into two equal parts,
where length DA = 5 miles, BD = 4 miles and AB = width = ?
Since each angle of a rectangle is right-angle, so triangle ABD will be a right-angled triangle.
Using Pythagoras theorem in triangle ABD, we have

Thus, the required width of the park is 3 miles.
Answer:
Step-by-step explanation:
Basically those lines next to the problem are absolute value signs. Get rid of those then your problem is solved.
Using Pythagorean’s theorem, the side length is sqrt(89)
