This is a perimeter question. Here, we are trying to find how far around the area is. The perimeter of a rectangle is equal to 2 times the length plus 2 times the width, or 2l+2w. In here, the length and width are both 6 feet, so we plug this in.
P=2l+2w
P=2*6 feet+2*6 feet
P=12 feet+12 feet=24 feet

Perform the indicated operation. (-18)/-(4)

Illusion [34]

A negative divided by a negative is always a positive. 4 can go into 18 only 4 times to get 16 with a remainder of 2. 2 is half of four, therefore -4 can go into -18 4.5 times.
The answer is 4 1/2 or 4.5.
I hope this helps ^-^

Please help!!! ABCD is a square with diagonals intersecting at E. What is the length of BE

Snezhnost [94]

Answer:

$BE = 4\sqrt2$

Step-by-step explanation:

Given

The attached square

Required

Find BE

First, we calculate BD (the diagonal) using Pythagoras theorem.

$BD^2 = BA^2 + AD^2$

Since the shape is a square, then

$BA = AD = 8$

So:

$BD^2 = 8^2 + 8^2$

$BD^2 = 2(8^2)$

Take square roots

$BD = \sqrt{2(8^2)$

$BD = \sqrt{2} * 8$

$BD = 8\sqrt{2}$

BE is half BD.

So:

$BE = \frac{1}{2} * BD$

$BE = \frac{1}{2} * 8\sqrt2$

$BE = 4\sqrt2$

PLEASE HELP!!!!!!!!!!

Montano1993 [528]

X is equal 25 degrees. Line ac goes though the parallel lines. So bcd is x. Cdb is 180-50 equals 130. All angles add to 180. 180-130 equals 2X. So x equals 25.
