C. 3x^4-x^3+3x^2+18x+4

D. 3x^4+x^3+x^2+x+4

Answers

ANSWER

$3 {x}^(4) - {x}^(3) + 3{x}^(2) + 18x + 4$

EXPLANATION

We want to multiply;

$(3 {x}^(2) + 5x + 1)( {x}^(2) - 2x + 4)$

We use the distributive property to obtain:

$3 {x}^(2) ( {x}^(2) - 2x + 4) + 5x( {x}^(2) - 2x + 4) + 1( {x}^(2) - 2x + 4)$

We expand to get:

$3 {x}^(4) - 6 {x}^(3) + 12 {x}^(2) + 5 {x}^(3) - 10 {x}^(2) + 20x + {x}^(2) - 2x + 4$

Regroup similar terms:

$3 {x}^(4) - 6 {x}^(3) + 5 {x}^(3) + 12 {x}^(2) - 10 {x}^(2) + {x}^(2) + 20x - 2x + 4$

Combine similar terms:

$3 {x}^(4) - {x}^(3) + 3{x}^(2) + 18x + 4$

The correct choice is C.

Final answer:

To multiply polynomials using the vertical multiplication method, multiply each term of one polynomial by each term of the other polynomial and then combine like terms.

Explanation:

To multiply the polynomials using the vertical multiplication method, we need to multiply each term of one polynomial by each term of the other polynomial and then combine like terms. Here are the steps:

Multiply the first term of the first polynomial by each term of the second polynomial.
Multiply the second term of the first polynomial by each term of the second polynomial.
Multiply the third term of the first polynomial by each term of the second polynomial.
Add up all the products to get the final result.

Applying these steps, the correct answer to the given multiplication is

$Option A: 3x^4 - x^3 + 3x^2 + x + 4.$

Which term can be used in the blank of 36x^3−22x^2−__ so the greatest common factor of the resulting polynomial is 2x? Select two options. 1) 2
2) 4xy
3) 12x
4) 24
5) 44y

Answers

Answer:

Option 2 and 3

Step-by-step explanation:

Given : Expression $36x^3-22x^2-\_$

To find : Which term can be used in the blank of expression so the greatest common factor of the resulting polynomial is 2x ?

Solution :

From the following options first we have to determine that it contain 2x.

1) 2- x is missing

2) 4xy - 2x is present

So, $36x^3-22x^2-4xy=2x(18x^2-11x-2y)$

3) 12x - 2x is present

So, $36x^3-22x^2-12x=2x(18x^2-11x-6)$

4) 24 - x is missing

5) 44y - x is missing

Therefore, The required terms are 4xy and 12x.

So option 2 and 3 is correct.

Answer:

2) 4xy

3) 12x

Step-by-step explanation:

You can figure this out by seeing which answer can have a 2x factored out of it.

4xy = 2x(2y)

12x = 2x(6)

The other answers dont have an x in it so you cant factor out a 2x from them.

What is the ratio of ounces to pounds in the weight of an object

Answers

Answer:

1 : 0.0625

Step-by-step explanation:

We are asked to find the ratio of ounces to pounds in the weight of an object.

We know that 1 pound equals 16.

Ratio of pound to ounce= 1 : 16

To find the ratio of ounces to pounds, we will divide 1 by 16.

$(1)/(16)=0.0625$

Ratio of ounce to pound= 1 : 0.0625

Therefore, our required ratio is 1 : 0.0625.

1 Pound = 16 Ounces
1 Ounce = 0.0625 Pounds

The ratio of the radii of two circles is 4:9. What is the ratio of their circumferences?

Answers

It will be 4:9 as well.
Circumference = 2πr,
r1 : r2 = 4:9 so this means that 2πr1 : 2πr2 = 4:9, because 2π = constant

4/9; ratio is still the same
