Answer:

B) 3x^2+6x+4

Step-by-step explanation:

(6x+7+x^2)+(2x^2-3)

6x+7+x^2+2x^2-3

3x^2+6x+7-3

3x^2+6x+4

The sum of the polynomials is 3x² + 6x + 4.

Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.

Given are two polynomials whose sum has to be found.

(6x + 7 + x ²) and (2x² - 3).

The sum of the polynomials is,

(6x + 7 + x ²) + (2x² - 3)

We have to operate the like terms together.

= (6x) + (7 - 3) + (x² + 2x²)

= 6x + 4 + 3x²

= 3x² + 6x + 4

Hence the sum of the polynomials is 3x² + 6x + 4.

Answer:

There right there u don't see it?

Answer:

the solution is (-8, 4)

Step-by-step explanation:

Let's use the addition/subtraction method here to eliminate one variable:

-x+y=4

x+3y=4

Combining these two equations results in

4y = 8, so that y = 2.  Substituting y = 2 into the second equation, we get:

x + 3(2) = 4, or x = -2.

Then the solution is (-8, 4)

Answer:

x = 7/3 or 2.33

Step-by-step explanation:

x3 + 1 = 8

x3 = 8 - 1

x3 = 7

x = 7/3 or 2.33

HOPE THIS HELPS YOU!! :)

Answer: x = 2

Step 1.

In order to solve this non-linear equation, we need to move all the terms to the left side.

In x³ + 1 = 9...

- term 1, will be moved to the right side.

Notice that a term changes sign when it 'moves' from one side of the equation to the other.

Rewrite the equation like this:  (x³ + 1) + (-1) = 9 + (-1)

Step 2.

Add x³ + 1 + (-1)

x³ + 1 + (-1) = 8

Now, x = 8.

Step 3.

In this non-linear equation, the variable needs to be isolated.

This is accomplished when both sides are exponentiated by the reciprocal of the variable's exponent, which in our example, 1/3 is equal to

Notice that since we exponentiated a simplified fraction with an odd denominator, only one solution has been created.

Rewrite the equation: [tex](x^3)^\frac{1}{3} =8^\frac{1}{3}[/tex]

Step 4.

We need to exponentiate the power.

The following rule is applied: [tex](A^B)^C=A^B^C[/tex]

According to the formula,

A = X

B = 3

C = 1/3

Rewrite the equation: [tex]x^3^\times^\frac{1}{3} =(2^3)^\frac{1}{3}[/tex]

Step 5.

We need to reduce this fraction, the 3 in x to the lowest terms.

This can be done by dividing out those factors that appear both in the numerator and in the denominator.

In our example, 3 is the common factor.

Rewrite the equation: [tex]x=2^\frac{3}{3}[/tex]

Step 6.

Lastly, we'll need to do the same thing as we did in step 5. Reduce the fraction in [tex]x=2\frac{3}{3}[/tex]. This can be done by dividing out those factors that appear both in the numerator and in the denominator.

Hence, the common factor is 3 since it occurs both in the numerator and the denominator.

Hence, x = 2.

the answer is 63.62 for 1 circle then multiply by 24 which gets 1526.88

Step-by-step explanation:

Answer:

Yes. In order for a shape to be qualified as a parallelogram It has to have 4 main properties. Opposite sides are parallel. Opposite sides have to be congruent. The opposite angles are congruent. Consecutive angles are supplementary (adds to 180-degrees). A rectangle qualifies all of these properties for a parallelogram. Opposite sides are parallel which works for a rectangle since they never intersects with the oppposit line. Opposite sides are congruent or equal which is also true becuase when looking at any 2 opposite sides of a rectangle, its always gonna be equal. Opposite angles are congurent which is also true because their all 90 degrees all are equal. And finally consecutive angles add up to 180. Soncsuive int his case basically means the angle next to that angle but we don’t have to worry about that since all angles of a rectangle are 90 and 90+90=180 so it also DOES qualify for a parallelogram.

Answer: 79%

Step-by-step explanation:

Javon's first 3 quizzes had a mean score of 90%. This means that his total score will be:

= 90% × 3

= 270%

Since he scores 46% on his next quiz, we add it to the previous score and this will be:

= 270 + 46

= 316

Then, his mean quiz score for these 4 quizzes will be:

= Total score / Number of quizzes

= 316 / 4

= 79%

Answer:

79%

Step-by-step explanation:

316 / 4 = 79%

Answer:

2x - y + 2 = 0 is the equation

y = 2x + 2 is the equation in slope-intercept form

Step-by-step explanation:

slope = (y₂ - y₁) / (x₂ - x₁)

slope = (6 - 8) / (2 - 3)

slope = -2 / -1

slope (m) = 2

equation through the points (3,8) and (2,6):

(y - y₁) / (y₂ - y₁) = (x - x₁) / (x₂ - x₁)

(y - 8) / (6 - 8) = (x - 3) / (2 - 3)

(y - 8) / -2 = (x - 3) / -1

-y + 8 = -2x + 6

2x - y + 2 = 0

slope-intercept form,

y = mx + c

y = 2x + 2

Answer:

Cream = 3 cups

Chocolate = 6 cups

Step-by-step explanation:

Cream = 1 cup

Chocolate = 2 cups

Total = 3 cups

Cream : chocolate = 1 : 2

He uses 9 cups of these two ingredients. How many cups of chocolate does he use in this candy recipe?

Cream = ratio of cream/total ratio of total cups

= 1/3 of 9

= 1/3 × 9

= 3 cups

Cream = 3 cups

Chocolate = ratio of chocolate/total ratio of total cups

= 2/3 of 9

= 2/3 × 9

= 6 cups

Chocolate = 6 cups

Answer:

2x^2 + x + 4

Step-by-step explanation:

Use Polynomial division.

The value after divide will be;

⇒ 2x² + x + 4

Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications. For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.

Given that;

The expression is,

⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7)

Now,

Since, The expression is,

⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7)

Divide the expression as;

⇒ 3x + 7 ) 6x³ + 17x² + 19x + 28 ( 2x² + x + 4

               6x³ + 14x²

             -       -

           ----------------------

                        3x² + 19x

                        3x² + 7x

                      -       -

                    --------------------

                              12x + 28

                              12x + 28

                            -       -

                           -------------------

                                0

Thus, The solution is,

⇒ 6x³ + 17x² + 19x + 28 ÷ (3x + 7) = (2x² + x + 4)

Answer:

6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8

Step-by-step explanation:

Given the following expression

6⋅10^ −2 and 2 ⋅ 10^− 8

Taking their ratio

k = 6⋅10^ −2/2 ⋅ 10^− 8

k = 6/2 * 10^-2/10^-8

k = 3 * 10^{-2+8}

k = 3* 10^6

Hence 6⋅10^ −2 is 3* 10^6 greater than 2 ⋅ 10^− 8
