2x^3 + 3x^2 -11x -6 divided by x - 2

Answers

p(x)= x-2

g(x)= 2x^3 + 3x^2 - 11x - 6

first we have to find the zero of the polynomial of x-2

p(x)= x-2 = 0

         x=2

therefore,

p(x)= 2x^3 + 3x^2 - 11x - 6

p(2)= 2*2^3 + 3*2^2 - 11*2 - 6

      = 2*8 + 3*4 - 11*2 - 6

      = 16 + 12 - 22 - 6

      = 28-28

     = 0

For problem 17a) your answer is: x=11.5 degrees

Step-by-step explanation:

1. Measure of angle BCA will be 180°-124°=46°

2. In triangle BCA, you now have two angles. 46 degrees, and 2x.

3. Measure of angle ABE is an exterior angle of triangle BCA

4. Using the exterior angle theorem, angle ABE=angle BCA+angle BAC

5. substitute!! 2x+46=6x

6. move 2x over and then divide by 4, you get x=11.5°

7. You can plug the answer back in to check if it correct!! have a nice day :>

The length of a rectangular room is 8 feet more than twice the width. If takes perimeter of the room is 124 feet, what are its dimensions?

Answers

Hey there! I'm happy to help!

Let's call the length and width L and W respectively.

L=2W+8

2W+2L=124

We plug our value of L into the second equation and solve for W.

2W+2(2W+8)=124

We undo the parentheses with the distributive property.

2W+4W+16=124

Combine like terms.

6W+16=124

Subtract 16 from both sides.

6W=108

Divide both sides by 6.

W=18

We plug this W value into the first equation to solve for L.

L=2(18)+8

L=36+8

L=44

So, the length is 44 feet and the width is 18 feet.

Hi there! :)

t ≥ -2

2t + 8 ≥ -4(t + 1)

Distribute the coefficient outside of the parenthesis:

2t + 8 ≥ -4(t) -4(1)

2t + 8 ≥ -4t - 4

Add 4t to both sides:

6t + 8 ≥ -4

Subtract 8 from both sides:

6t ≥ -12

Divide both sides by 6:

t ≥ -2.

Answer: t ≥  -2/3

Step-by-step explanation:

Distribute the -4 into (t + 1). 2t + 8 ≥  - 4t - 4Add 4t on both sides. 6t + 8 ≥  -4Subtract 8 on both sides. 6t ≥  -4Divide by 6 on both side. Then , simplify -4/6 by 2 on both the numerator and denominator. t ≥ -2/3

Answers

Answer:

A. 37

Step-by-step explanation:

(fxg) (10)

Step 1.  G is the second letter, so we first use the equation g(x) = x-4

Step 2.  Plug in ten for x.   g(x) = 10-4

Step 3.  ten minus four is six.  g(x) = 6

Step 4.  Now the new x is 6 and we use the second equation next.

f(x) = x^2 + 1

Step 5.  Plug in six for x. f(x) = 6^2 + 1

Step 6.  six to the power of two is 36. f(x) = 36 + 1

Step 7.  36 plus one is 37. f(x) = 37

Step 8.  Answer is thirty seven!!!! Cheer!!!!

January, Scott earned $8,999. In February, he earned $2,387 more than in January. In March, Scott earned the same amount as in February. How much did Scott earn altogether during those three months?

Answers

Answer:I believe it's 31,771

Step-by-step explanation: you first need to add 8,999 + 2,387 to get 11,386 then add 11,386 + 11,386 to get 22,772 and then add 8,999 to get 31,771.

Scott earns $31,771 altogether during those three months.

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

We have to determine that Scott earn altogether during those three months.

We have been given that in January, Scott earned $8,999.

In February, he earned $2,387 more than in January.

So we have to add the amount of January and 2,387, we get

⇒ 8,999 + 2,387 = 11,386

In March, Scott earned the same amount as in February.

So the amount of March = 11,386

Therefore, He earns altogether during those three months as

⇒ 8,999 + 11,386 + 11,386

Apply the Addition operation in the above expression,

⇒ 31,771

Hence, Scott earns $31,771 altogether during those three months.
