The polynomial correctly combines the like terms and puts the given polynomial in standard form is \rm 8x^6+ 8x^4y^2 - 5x^3y^3 +x^2y^4 -7xy^5.

The correct option is D.

Given

Expression; \rm -5x3y^3 + 8x4y^2 - xy^5 - 2x2y^4 + 8x^6 + 3x^2y^4 - 6xy^5

<h3>What is polynomial?</h3>

A polynomial is an expression consisting of coefficients and variables which are also known as indeterminates.

We have to combine the like terms which means the terms with the same degree.

Therefore,

The correctly combines the like terms;

\rm =-5x^3y^3 + 8x^4y^2 - xy^5 - 2x^2y^4 + 8x^6 + 3x^2y^4 - 6xy^5\\\\=8x^6 +8x^4y^2--5x^3y^3+ 3x^2y^4- 2x^2y^4 - xy^5 -6xy^5\\\\= 8x^6+ 8x^4y^2 - 5x^3y^3 +x^2y^4 -7xy^5.

Hence, the polynomial correctly combines the like terms and puts the given polynomial in standard form is \rm 8x^6+ 8x^4y^2 - 5x^3y^3 +x^2y^4 -7xy^5.

Does Y= -2/3x + 3 &amp; Y=2/3x + 2 have unlimited solutions?
notsponge [240]

Answer:

x = 3/4

y = 2.5

Step-by-step explanation:

No there is just one.

Equate the ys

-2/3 x + 3 = 2/3 x + 2                        Add 2/3 x to both sides

3 = 2/3 x + 2/3x + 2                          Combine

3 = 4/3 x + 2                                     Subtract 2

3-2 = 4/3 x                                        Multiply by 3

1 * 3 = 4x                                          Divide by 4

3/4 = x

====================

y = 2/3 x + 2

y = 2/3 * 3/4 + 2

y = 6/12 + 2

y = 1/2 + 2

y = 2 1/2

y = 2.5

(Right angle Trigonometry) help me solve for X please!
Vinvika [58]

Answer:

x = 52.0

Step-by-step explanation:

Reference angle = 68°

Length of side Opposite to reference angle = x

Adjacent length = 21

Apply the trigonometric function, TOA, which is given as:

Tan 68° = Opp/Adj

Substitute

Tan 68° = x/21

21 × Tan 68° = x

51.9768238 = x

x = 51.9768238 ≈ 52.0 (approximated to nearest tenth)

Factor –7x3 21x2 3x – 9 by grouping. what is the resulting expression? (3 – 7x)(x2 – 3) (7x – 3)(3 x2) (3 – 7x2)(x – 3) (7x2 – 3
juin [17]

The factors of the expression are \rm(3 - 7x^2)(x - 3)

<h3>How to find factors in the expression?</h3>

First group the first two terms and the last two terms together respectively.

The factors of the expression are given by;

\rm= -7x^3 + 21x^2 + 3x - 9\\\\=-7x^2(x - 3) + 3(x - 3)\\\\=(3 - 7x^2)(x - 3)

Hence, the factors of the expression are \rm \rm(3 - 7x^2)(x - 3).

If the vertices of / are B(–3, 3), C(3, 5), and D(–1, 0), what is the perimeter
Rasek [7]
Best is to draw a sketch of the three points.
Next step is to find the distances BC, CD, DB.
The perimeter is the sum of the three distances.

The distances are found using the distance formula:
D=sqrt((y2-y1)^2+(x2-x1)^2)
order of (x1,y1), (x2,y2) is not important.
BC=sqrt((3- -3)^2+(5-3)^2)=sqrt(6^2+2^2)=sqrt(40)=5.324
CD=sqrt((-1-3)^2+(0-5)^2)=sqrt(4^2+5^2)=sqrt(41)=6.403
DB=sqrt((-3- -1)^2+(3-0)^2)=sqrt(2^2+3^2)=sqrt(13)=3.606
So perimeter = BC+CD+DB=16.333  (approximately)
