Multiply the polynomial x (3x-1)(2x+5) also what is the degree of the polynomial

Answers

Answer:

Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]

Degree of polynomial = 3

Step-by-step explanation:

The given polynomials are:

[tex]x(3x-1)(2x+5)[/tex]

In order to multiply the given polynomials we have to work step by step. First of all the polynomials in the bracket will be multiplied and then their result will be multiplied with x.

So, multiplying the polynomials in round brackets first

[tex]=x(3x-1)(2x+5)\\= x\{3x(2x+5)-1(2x+5)\}\\=x\{6x^2+15x-2x-5\}\\=x(6x^2+13x-5)[/tex]

Now multiplying with x

[tex]= 6x^3+13x^2-5x[/tex]

Degree of a polynomial is the highest exponent of variable in the polynomial.

In the acquired result, the highest exponent of x is 3 so the degree is 3.

Hence,

Result after multiplication of polynomial is: [tex]6x^3+13x^2-5x[/tex]

Degree of polynomial = 3

b). Kirchoff has more money than Maxi. If Kirchoff gave Maxi $20, they would have the
same amount. While it Maxi gave Kirchoff $22, Kirchoff would then have twice as much as
Maxi. How much does each one actually have?

Answers

Answer:

k = 146

m= 106

Kirchoff has $146

Maxi has $106

Step-by-step explanation:

For the purpose of the equations, I’ll call Kirchoff and Maxi a and b respectively.

a - 20 = b + 20 (equation 1)

2(b - 22) = a + 22 (equation 2)

We can juggle those around for

a = b +40 (equation 1r (re-arranged)) and

2b - 44 = a + 22 so 2b - 66 = a (equation 2r (rearranged))

The equations are now:

a = b + 40 (new equation 1) and

a = 2b - 66 (new equation 2)

Substitute from new equation 1 to new equation 2:

b + 40 = 2b - 66 so 40 = b - 66 making b = 106.

Plug b = 106 into new equations 1 and 2 for:

a = 106 + 40 (new equation 1) and

a = 212 - 66 (new equation 2)

This gives a = 146 and b = 106

TEST: There’s a gap of $40, so giving $20 from a to b makes them equal.

SECOND TEST: Subtracting $22 from b makes it $84 and giving that sum to a makes it $168, twice as much. The tests work.

Kirchoff has $146 and Maxi has $106.

In geometry, a set of points in space are coplanar if there exists a geometric plane that contains them all. For example, three points are always coplanar, and if the points are distinct and non-collinear, the plane they determine is unique. In other words, to be coplanar, all points have to lie in the same plane. Point d is not in the plane, therefore all points except d, are non coplanar.

− 3/4 is a rational number, but not an integer. Explain why below.

Answers

A rational number is any number that can be expressed as a fraction. An integer is a whole number. -3/4 is a fraction but not a whole number, so it is rational but not an integer.

− 3/4 is not an integer but a a rational number.

Why is this correct?

A rational number is simply a number that can be written as a fraction with both the numerator and denominator being integers (where the denominator's not zero). For instance lets consider 3/4 as an example. It can be expressed as the fraction 3/4, where 3 and 4 are both integers.

On the hand an integer is a number that is not, in the form of a fraction. In the case of 3/4 it cannot be classified as an integer since it represents a fraction, than a whole number.

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 angles and equate to 180, that is

a + 8 + 2a + 43 = 180

3a + 51 = 180 ( subtract 51 from both sides )

3a = 129 ( divide both sides by 3 )

Every Saturday morning for as long as I can remember I have seen him leave, always by himself, to look for treasure. I have always longed to go with him, and hes always told me that someday I would get the chance. I was so excited when he told me I would finally have my chance that I was bouncing off the walls like a rubber ball and springing from one place to the next the rest of the day.He has always been as quiet as a mouse about the treasure that he finds, scurrying away with his equipment in the morning and piling up his treasure in his study. Even though he says he always comes home with something, he has never shown it to me or even told me what type of treasure it is. Is it gold, or silver, or maybe its precious jewels? Whatever it is, tomorrow I will find out, and hopefully hell let me bring some to class so that I can show my friends since Ive been bragging about it to them ever since Dad told me I could go!Saturday, April 3The treasure hunt was fun, but it was not what I expected. Dad and I left early in the morning and headed for the same woods that we sometimes go hiking in on Sundays. I never would have thought they hold treasure, but what was really odd was when Dad told me to leave the shovels at home because we wouldnt need them. But what he did bring with him was a bright yellow GPS . I had seen it in his truck many times before. I always wondered what he did with it. Today I found out.Dad and I wandered into the woods, first staying on the hiking path I had taken several times before and then veering off the path. The forest was like a statue; it was still and covered in damp moss and dead leaves; it didn't even seem alive. It appeared that no one had been there for a long time so I knew that this treasure must be old and far under the ground. How were we going to get to it without shovels?As Dad kept his eyes on the GPS , I looked around, and suddenly I noticed a patch of leaves that was disturbed and a log that looked like it had been moved. When I asked Dad about it, his eyes lit up, and he said he saw the treasure. He reached under the log and pulled out a plastic box with a label that read Official Geocache.I didnt know what an official geocache was, but I soon found out when Dad opened it. Inside was a little notebook and a bunch of small items like a set of dice, a toy car, and a large silver dollar. Dad said that he thought the toy car was cool, so he took it out and put it in his pocket and then pulled a golf ball from his other pocket and put it in the box. He wrote his name and my name in the little notebook and then closed the box and put it back where he found it.Geocaching, which is what Dad later told me this type of treasure hunting is called, was much different than digging for gold in the ground. But I thought it was fun, and I hope Dad takes me again next Saturday.Part AIn "Nicholas's Diary: April 2 and 3," what is Nicholass first thought when he and his father leave home to go treasure hunting?It is not going to be the type of treasure hunt that he thought it would be.He will not be finding gold or silver, but something far more important.He will not have a very good story to tell his friends at practice on Monday.The treasure will be carefully hidden and closely guarded.Question 2Part BWhich sentence from the text best supports the answer in Part A?what was really odd was when Dad told me to leave the shovels at home because he said we wouldnt need them.As Dad kept his eyes on the GPS , I looked around, and suddenly I noticed a patch of leaves that was disturbed and a log that looked like it had been moved.Dad and I left early in the morning and headed for the same woods that we sometimes go hiking in on Sundays."The forest was like a statue; it was still and covered in damp moss and dead leaves; it didn't even seem alive."
