Answer:

441 inches^{2}

Step-by-step explanation:

If this is a rectangle, meaning the width and the legnth is different, there is no way in solving this.

However, if it is a square, meaning all the sides are the same,

we can know that every side is 21 inches long.

An area is the width times the length, which is both 21 in this case.

21 times 21 = 441.

441 inches squared.

Answer:

Dustin has 42 cards.

Mike has 54 cards.

Kevin has 39 cards

Step-by-step explanation:

subtract (Dustin + Mike) – (Dustin + Kevin) or 96 – 81.

Think of it like....

Dustin + Mike – Dustin – Kevin

Dustin – Dustin + Mike – Kevin

Mike – Kevin

Since 96 – 81 = 15, Mike – Kevin = 15

Add (Kevin + Mike) + (Mike – Kevin) or 93 + 15.

Think of it like...

Kevin + Mike + Mike – Kevin

Kevin – Kevin + Mike + Mike

Mike + Mike

Since 93 + 15 = 108, Mike + Mike = 108. If you divide, Mike had 54 cards. That means that you can find Kevin’s cards by using 93 – 54 or 39. You can then find Dustin’s cards by using 81 – 39 = 42.

Check:

Dustin’s cards + Kevin’s cards = 42 + 39 = 81

Dustin’s cards + Mike’s cards = 42 + 54 = 96

Mike’s cards + Kevin’s cards = 54 + 39 = 93

What is the square root of 82
Andru [333]

Well, the square root of 82 is an irrational number, so
it can never be completely written with digits.  As a
decimal, it goes on and on forever, and never ends. 
As a fraction, it can't be written at all.

The square root of  82  is approximately  9.055 .

(That number is about  0.0043%  too small, which is pretty close.)
