Answer: 3 and 8 have the common number or denominator 24 because 3 times 8 is 24
Answer 2
Answer: 3/8 and 1/3 = 3/8+1/3  24 is the common denominator. 3x3=9 8x3=24 1x8 =8 3x8=24

What is the additive inverse of the polynomial? -7y^2+x^2y-3xy-7x^2

Answers

Answer:

Additive inverse is  (7y² - x²y + 3xy + 7x²).

Step-by-step explanation:

Let the additive inverse of the given polynomial be Y.

Therefore as per definition of additive inverse of any polynomial the addition of a polynomial and additive inverse of any polynomial is always zero.

So Polynomial + additive inverse polynomial = 0

(-7y² + x²y - 3xy - 7x²) + Y = 0

Y = -(-7y² + x²y - 3xy - 7x²) = (7y² - x²y + 3xy + 7x²)

So the additive inverse of the polynomial will be (7y² - x²y + 3xy + 7x²).

Answer:

The answer is A

Step-by-step explanation:

The additive inverse is basically the opposite symbol for the numbers.

So, therefore:

What is the additive inverse of the polynomial?

-7y^2 + x^2y - 3xy - 7x^2

The answer to this would be

7y^2 - x^2y + 3xy + 7x^2

You can buy 2 DVDs for the same price you would pay for 3 CDs selling for $13.20 a piece.Explain how you could find the price of 1 DVD.

Answers

So,

3 CD's sell for $13.20 each.
3 * 13.20 = $39.60

$39.60 is also the price for 2 DVD's.

Divide $39.60 by 2.
$19.80

Each DVD is $19.80.
