(x-y) (x²-2xy + y²)​

Answers

Answer 1

Answer:

x³ - 2x²y + 3xy² - y³

Step-by-step explanation:

When multiplying with two brackets, you need to multiply the two terms, (x) and (-y) from the first bracket to all the terms in the second brackets, (x²), (-2xy) and (y²) individually. I have put each multiplied term in a bracket so it is easier.

(x-y)(x²-2xy+y²) =

(x × x²) + {x × (-2xy)} + (x × y²) + {(-y) × x²) + {(-y) × (-2xy)} + {(-y) × y²)

Now we can evaluate the terms in the brackets.

(x × x²) + {x × (-2xy)} + (x × y²) + {(-y) × x²) + {(-y) × (-2xy)} + {(-y) × y²) =

(x³) + (-2x²y) + (xy²) + (2xy²) + (-y³)

We can open the brackets now. One plus and one minus makes a minus.

(x³) + (-2x²y) + (xy²) + (2xy²) + (-y³) = x³ - 2x²y + xy² + 2xy² - y³

Evaluate like terms.

x³ - 2x²y + xy² + 2xy² - y³ = x³ - 2x²y + 3xy² - y³

The cost of a pair of shoes is Rs. 1000 . The GST charged was '5%' . Find the bill amount andalso find share of CGST, and SGST.​

Answers

Answer:

Bill amount = Rs. 1050

CGST share = SGST share = Rs. 25

Step-by-step explanation:

We are told that the GST charged was 5% and cost of a pair of shoes is Rs. 1000. Thus;

Bill amount = 1000 + (5/100) × 1000

Bill amount = Rs. 1050

Now, CGST and SGST are both usually half of GST rate.

Thus;

CGST rate = SGST rate = 5%/2 = 2.5%

Thus;

CGST share = SGST share = 2.5% × 1000 = Rs. 25

find the x in the given triangle, step by step explanation please ​

Answers

Answer:

x = 42.67

Step-by-step explanation:

x + 2x + 7 + 45 = (3 - 2) * 180

3x + 52 = 180

   - 52       - 52

3x = 128

/ 3    / 3

x = 42.67

Every triangle is equal to 180 so add 45 and the other number then subtract from 180 to get x

Can sides of a triangle have lengths 3,4,9

Answers

Answer:

yes

Step-by-step explanation:

No, the lengths 3, 4, and 9 cannot form the sides of a triangle.

What is Triangle Inequality?

The triangle inequality is a fundamental geometric principle that states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

We have sides as 3, 4 and 9.

For a triangle to be valid, the sum of the lengths of any two sides must be greater than the length of the third side.

In this case, let's check if this condition is satisfied:

3 + 4 = 7

7 is less than 9

Therefore, these lengths do not satisfy the triangle inequality theorem, and a triangle cannot be formed with side lengths 3, 4, and 9.

Step-by-step explanation:

solve the equation for x. What was the cost of each raffle ticket?

In 2006 the average ticket price for a national football league game was 62.38. Since then the cost has increased an average of $2.54 per year. Write a linear equation to represent the cost of C of an NFL ticket y years after 2006.

Answers

Answer:

y = 2.54x + 62.38

Step-by-step explanation:

Let x represent the duration or stipulated years after the year 2006

Let y represent the amount of ticket that is sold

Let m represent the average increase in the price every year

y = mx + c

y = 2.54 × x + 62.38

y = 2.54x + 62.38

Answer:

C=2.54y+62.38

c=2.54y+62.38  

C=62.38+2.54y  

or

c=62.38+2.54y
