Will an object 20ft below sea level have a different absolute value than an object 20ft above sea level .. explain
trapecia [35]

No, the objects below the sea and above both have the absolute value of 20 ft.

The absolute value is how far the number is away from zero- it doesn't matter if it is in the positive or negative direction

For example, if you drove 20 miles from your house in one direction while your friends drove 20 miles in the other direction- both of  the distances of you and your friend from the your house is 20 miles.

Distance is a great example of the absolute value because it is always positive. It doesn't matter what direction, it is always 20 miles from your house.

The perimeter of a parallelogram is 76 inches and 1 side measures 14 inches of it can be determined what are the lengths in inch
nydimaria [60]

The dimension of the parallelogram ABCD will be 14 inches, 48 inches, 14 inches and 48 inches.

<h3>What is a parallelogram?</h3>

It is a polygon with four sides. The total interior angle is 360 degrees. A parallelogram's opposite sides are parallel and equal.

The perimeter of a parallelogram is 76 inches.0

And one side measure is 14 inches.

Then the rest of the sides will be

We know that opposite sides are prallel and equal.

Let ABCD is a parallelogram.

AB = CD = 14 inches

BC = AD = x

Then the value of x will be

We know

 P = 2(AB + BC)

76 = 2(14 + x)

 x = 48

More about the parallelogram link is given below.
