Answer:

-xy(3y - 5x)

Step-by-step explanation:

The only thing I can think of is that it has a common factor of -xy on either side of the plus sign.

-3xy^2 + 5x^2y = -xy(3y - 5x)

Answer:

The given polynomial has degree 3

$xy(3y + 5x)$

Step-by-step explanation:

$3xy^2 + 5x^2y$

The given polynomial has degree 3

we can factor the given expression

$3xy^2= 3*x*y*y$

$5x^2y = 5*x*x*y$

$3xy^2 + 5x^2y$

Both term has GCF xy, write xy outside and left out terms inside

$xy(3y + 5x)$

Write 5/8 and 9/14 so that they have a comon denominatr

valentina_108 [34]

The denominator is the bottom portion of the fraction. Example 4/6, the 6 is the denominator. The easiest way to start out in finding the common denominator is to see what number, 8 and 14, go into equally. Example: 1/4 and 1/3, 3 and 4 both go into 12. If you multiply 4 by 3 as well as 3 by 4 you get 12 both times. Now try it with 8 and 14.

What number can 8 and 14 go into equally? (56)

8x7=56...14x4=56

Three cards are drawn with replacement from a standard deck. What is the probability that the first card will be a diamond, the

noname [10]

Answer:

The probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen is 0.0096

Step-by-step explanation:

Total no. of cards = 52

No. of diamond cards = 13

No. of black cards = 26

No. of queens = 4

Three cards are drawn with replacement from a standard deck.

We are supposed to find he probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen

Probability of getting diamond card = $\frac{13}{52}$

Probability of getting black card = $\frac{26}{52}$

Probability of queen = $\frac{4}{52}$

Probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen = $\frac{13}{52} \times \frac{26}{52} \times \frac{4}{52}=0.0096$

Hence the probability that the first card will be a diamond, the second card will be a black card, and the third card will be a queen is 0.0096
