Find the distance between the points (-3, 5) and (6, -7)

Answers

Answer 1

Answer:

Hello,

6 - (-3) = 9

-7 - 5 = -12

$\sqrt{9^(2) +(-12)^(2) } = √(81 + 144) = √(225) = \sqrt{15^(2) } = 15$

Factor the GCF: −6x3y + 9x2y2 − 12xy33xy(−2x2 + 3xy − 4y2)

−3xy(2x2 + 3xy − 4y2)

−3xy(2x2 − 3xy + 4y2)

−3(2x3y − 3x2y2 + 4xy3

Answers

Answer:

Option C is the answer.

Step-by-step explanation:

We have to factor the GCF of the given expression:

-6x³y + 9x²y² - 12xy³

To get the GCF of the given expression we will find the factors of each term first.

Factors of 6x³y = 2 × 3 × (x) × (x) (x) (y)

Factors of 9x²y² = 3 × 3 × (x) (x) (y) (y)

Factors of 12xy³ = 2 × 2 × 3 × (x) (y) (y) (y)

So the common factor is 3 × (x) (y)

Now we will take out the GCF as a factor of the given expression = 3xy (-2x² + 3xy - 4y² )

= -3xy ( 2x² - 3xy + 4y² )

Option C is the answer.

-6x^3y + 9x^2y^2 - 12xy^3
-3xy(2x^2) - 3xy(-3xy) - 3xy(4y^2)
-3xy(2x^2 - 3xy + 4y^2)

The answer is C.

A piano has white keys and black keys in the ratio of 13 : 9. If there are 52 white keys,how many black keys are there?

Answers

✡ Answer: 9/36 ✡

- - Why?

Because if you look at it like this:

$(13)/(52) = (9)/(36)$

- 52 being the white and 36 because the black.

✡Hope this helps✡

Let w = white and b = black.
Using the proportion,
13/w = 9/b
Since w = 52 white keys, therefore
13/52 = 9/b
b = 36 black keys
