Answer:

4x+12y = 4 (x+3y)

35x+50y = 5 (7x+10y)

18x+9y = 9 (2x+y)

32x+8y = 8 (4x+y)

100x+700y = 100 (x+7y)

Step-by-step explanation:

You basically have to figure out what x and y are being divided by to get the x and y on the other side and put that before the parenthesis. For example in the first question in order to get x you must divide 4x by 4 and to get 3y you must divide 12y by 4 as well.

(x³ + ³) / (x - y) Do not include parentheses in your answer.

Lubov Fominskaja [6]

The simplified expression of $\frac{x^3 + (-y)^3}{(x - y}$ is $x^2+xy+y^2$

<h3>Complete question</h3>

Simplify the expression: (x³ + (-y)³) / (x - y)

Do not include parentheses in your answer.

<h3>How to simplify the expression?</h3>

The expression is given as:

$\frac{x^3 + (-y)^3}{(x - y}$

Open the inner bracket

$\frac{x^3 -y^3}{(x - y}$

Apply the difference of two cubes to the numerator

$\frac{(x-y)(x^2+xy+y^2)}{(x - y}$

Cancel out the common factors

$x^2+xy+y^2$

Hence, the simplified expression of $\frac{x^3 + (-y)^3}{(x - y}$ is $x^2+xy+y^2$

What is the common difference, d, in the arithmetic sequence defined by the formula below? an=2n+1

marishachu [46]

<h3>Answer:</h3>

d = 2

<h3>Solution:</h3>

We are given that the arithmetic progression is defined by :

➝ 2n + 1

Therefore, 

For first term

➙ n = 1

➝ 2 × 1 + 1

➝ 2 + 1

➝ 3

For second term

➙ n = 2

➝ 2 × 2 + 1

➝ 4 + 1

➝ 5

Common difference

➙ 2nd term - 1st term

➝ 5 - 3

➝ 2

<h3>More information:</h3>

The difference between the successive term and the preceding term is the difference of an arithmetic progression. It is always same for the same arithmetic progression.
