70% of what number is 50

Answer:

x6 − x3 − 20 = (x3)2 − x3 − 20 = (x3 + 4)(x3 − 5)

Step-by-step explanation:

In this trinomial, the exponent of the first term, 6, is double the exponent in the second term, 3. And, the third term contains no variables. So, we can factor the expression as we would a quadratic, but treating x3 as if it were x:

Answer:

(x³ - 5)(x³ + 4)

Step-by-step explanation:

Consider the factors of the constant term (- 20) which sum to give the coefficient of the x³ term (- 1)

The factors are - 5 and + 4, since

- 5 × 4 = - 20 and - 5 + 4 = - 1, hence

- x³ - 20 = (x³ - 5)(x³ + 4)

Answer:

3

Step-by-step explanation:

-x = 3 -4x + 6

Add 3 and 6.

-x = -4x + 9    * add 4x to itself and -x

+4x = 4x + 9  * -4x + 4x would cancel out so..

3x = 9   * divide

x = 3

Final answer:

Since 0 = 9 is not true, there is no value of x that satisfies the equation.

Explanation:

To find the value of x in the equation −x = 3 − 4x + 6, we need to isolate the variable x. We can start by combining like terms on the right side of the equation:

1. -x = -x + 9

Next, we can add x to both sides of the equation to eliminate the -x term:

1. 0 = 9

Since 0 = 9 is not true, there is no value of x that satisfies the equation. Therefore, the answer is None of the above.

The multiplication of 1,537×242 is 371,954.

What are Arithmetic operations?

Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.

+ Addition operation: Adds values on either side of the operator.

For example 4 + 2 = 6

- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.

for example 4 -2 = 2

* Multiplication operation: Multiplies values on either side of the operator

For example 4*2 = 8

/ Division operation: Divides left-hand operand by right-hand operand

For example 4/2 = 2

We have been given that 1,537×242

To determine the multiplication of 1,537×242

⇒ 1,537×242

⇒ 371954

Thus, the multiplication of 1,537×242 is 371,954.

Answer:

4 sets.

Step-by-step explanation:

We are asked to find the greatest number of sets you can make using 28 pens and 80 pencils.

To solve our given problem, we will find greatest common factor of 28 and 80.

Factors of 28: 1, 2, 4, 7, 14, 28.

Factors of 80: 1, 2, 4, 5, 8, 10, 16, 20, 40, 80.

We can see that the greatest common factor of 28 and 80 is 4, therefore, you can make at-most 4 sets each having same number of pens and pencils.
