GiveN:

ABCD is a parallelogram.
AC and BD are the diagonals.
DE = 28 units

To FinD:

Value of x in length of BE?

Step-wise-Step Explanation:

We know that $,$

In any parallelogram, the diagonals (lines linking opposite corners) bisect each other. Then, AE = EC for diagonal AC and BE = DE for diagonal BD.

⇒ BE = DE

⇒ x - 4 = 28 units

⇒ x = 32 units

Hence, The required value of x here is 32 units.

If three times the smaller of two consecutive integers is added to four times the larger,the result is 39

murzikaleks [220]

Let n be the smaller integer.

Step 2. Let n+1 be the larger and next consecutive integer.

Step 3. Let 3n be three times the smaller integer.

Step 4. Let 4(n+1) be four times the larger integer.

Step 5. Then 3n+4(n+1)=39 since three times the smaller of two consecutive integers is added to four times the larger will result in 39.

Step 6. Solving the equation in Step yields the following steps:

stWith n=5, then n+1=6 and check the sum 3*5+4*6=15+24=39...which is a true statement.

Step 7. ANSWER: The integers are 5 and 6

I hope the above steps were helpful.heyaaa

thanx

A submarine was situated 800 feet below sea level.

Ghella [55]

Answer:

New position = -525 ft or 525 ft below the sea level

Step-by-step explanation:

Lets h be the height of the sea.

Given:

A submarine was situated 800 feet below sea level.

It is ascends 275 feet.

We know that h = 0 on the surface of the sea.

When we go below the surface vertically inside the sea the height will become negative.

So the submarine was situated h = -800 feet below the sea level, and it is ascends 275 feet from -800 feet.

So the new height of the submarine is.

$h = -800 + 275$

$h = -525\ ft$

Therefore the new position of the submarine is 525 below the sea level.
