Answer:

x=2

Step-by-step explanation:

Multiply -3 with the first parenthesis and 6 with the second parenthesis then you combine like terms so you do the opposite and add three to both sides (Add 3 to 6) and combine the other numbers so add one to 4 which makes five then subtract 5 from both sides and divide 3 from 9

Answer:

x=2

Step-by-step explanation:

-3(x+4)=(-x-1)

-3x-12=6(-x-1)

-3x-12=-6x-6

-3x-12+12=-6x-6+12

-3x=-6x+6

-3x+6x=6x+6+6x

3x=6

3x/3= 6/3

x=2

What is negative 6x squared take away 586 =84x take away 4
olchik [2.2K]

Answer:

This equation has no real roots

Step-by-step explanation:

We want to solve

- 6 {x}^{2}  - 586 = 84x - 4

We group all terms on the left:

- 6 {x}^{2}  - 84x - 586 + 4 = 0

- 6 {x}^{2}  - 84x - 582= 0

Divide through by -6

{x}^{2}  + 14x + 97 = 0

The discriminant is

{14}^{2}  - 4 \times 1 \times 97 =  - 192

This means the given equation has no real solution, since the discriminant is less than 0

Move the digits in 625,134 to create a
vredina [299]

Answer:

a. The new number created is 265,134.

b. The new number created is 625,314.

c. The new number created is 652,314.

d. The new number created is 462,513.

e. The new number created is 253,416.

Step-by-step explanation:

Note: The first question is not correctly and fully stated. It is therefore restated as the questions are answered as follows:

a. Move the 2 so it is worth 10 as much.

From 625,134, the 2 implies 20,000.

If we move the 2 so it is worth 10 as much, it implies that 20,000 is multiplied by 10 and the answer is as follows:

20,000 * 10 = 200,000

The answer implies that 2 becomes the first number and the new number created from 625,134 is as follows:

The new number created is 265,134.

b. Move the 3 so it is worth 10 times as much.

From 625,134, the 3 implies 30.

If we move the 3 so it is worth 10 as much, it implies that 30 is multiplied by 10 and the answer is as follows:

30 * 10 = 300

The answer implies that 3 becomes the fourth number and the new number created from 625,134 is as follows:

The new number created is 625,314.

c. Move the 5 so it is worth 50,000.

This implies that 5 becomes the second number and the new number created from 625,134 is as follows:

The new number created is 652,314.

d. Move the 4 so its value changes to 4 X 100,000

This implies that 4 is now 400,000 and it now becomes the first number. The new number created from 625,134 is as follows:

The new number created is 462,513.

e. Move the 1 and the 6 so that the sum of their values is 16.

This implies the one becoms 10 and the 6 becomes just 6.

As a result, this implies that the 1 now becomes the fifth number and the 6 now become the last number. The new number created from 625,134 is now as follows:

The new number created is 253,416.

Factor out the GCF from the polynomial.<br> 18x^6+ 81x^5 - 63x^2 +45
kramer

Answer:

The GCF is 9

Step-by-step explanation:

In the given polynomial 18x^6+ 81x^5 - 63x^2 +45  lets represent each term  as its factors

18x^6 = 2 \times 3 \times 3 \times x \times x \times x \times x \times x \times x

81x^5 = 3 \times 3 \times 3 \times  3 \times x \times x \times  x \times  x \times x

63x^2 = 3 \times 3 \times 7  \times  x \times x

45 = 3 \times 3 \times 5

The greatest common factors from each term  are  3 , 3

Thus the GCF =   3 \times 3 = 9
