Answer 1

Answer:

[tex] \boxed{ \bold{{ \boxed{ \sf{3 {x}^{3} + 17 {x}^{2} + 21x - 9}}}}}[/tex]

Option A is the correct option.

Step-by-step explanation:

[tex] \sf{( {x}^{2} + 6x + 9)(3x - 1)}[/tex]

Use distributive property

⇒[tex]{ \sf{ {x}^{2} (3x - 1) + 6x(3x - 1) + 9(3x - 1)}}[/tex]

⇒[tex] \sf{3 {x}^{3} - {x}^{2} + 18 {x}^{2} - 6x + 27x - 9}[/tex]

Collect like terms

⇒[tex] \sf{3 {x}^{3} + 17 {x}^{2} + 21x - 9}[/tex]

Hope I helped!

Best regards! :D

Answer 2

Answer:

3x^3 + 17x^2 + 21x - 9

Step-by-step explanation:

Use distributive property.

First distribute the 3x

3x times x^2 + 6x + 9. Distribute = 3x^3 + 18x^ 2 + 27x

Now we distribute the -1

-1 times x^2 + 6x + 9. Distribute = -x^2 -6x - 9

We Add both answers-

  3x^3 + 18x^2 + 27x

+               -x^2     -6x - 9

Answers

Answer:

x≤ 5

Step-by-step explanation:

18-2-1=15

15/3=5

Answer:

the number of book she can carry is 5 books

Step-by-step explanation:

backpack capacity = 18 lb

backpack can carry:

lunch = 1 lb

gym clothes = 2 lb

books = 3 lb per book

find:

how many books can she carry in her backpack?

backpack capacity = lunch + gym clothes +  x books

let x be the number of books

18 = 1 + 2 + 3x

18 - 1 - 2 = 3x

15 = 3x

x = 15 / 3

x = 5

therefore, the number of book she can carry is 5 books

Answers

Answer:

Deductive reasoning

Step-by-step explanation:

Deductive reasoning is when you make a conclusion based on facts you previously know. These conclusions are correct.

Inductive reasoning is when you use a previously known fact to come up with a general assumption.

Here, we took some previously known facts (If anyone takes vitamins, they will feel better) and made a conclusion that relates fully to that fact. Since Bob took vitamins, he will feel better.

The number of sides of two regular polygons are as 5:4 and the difference between their angles is 9°. Find the number of sides of the polygons,

Answers

Answer:

8 and 10.

Step-by-step explanation:

I am assuming the difference of 9° is between their interior angles.

The formula for the interior angle of a regular polygon is 180° - 360°/n, where n is the number of sides.

As the number of sides increase, the interior angle increases.

Therefore 180° - 360°/(5x) = 180° - 360°/(4x) + 9°.

180° - 360°/(5x) = 180° - 360°/(4x) + 9°

360°/(4x) = 360°/(5x) + 9°

90°/x = 72°/x + 9x°/x

=> 90° = 72° + 9x°

9x° = 18°

x = 2.

Hence the number of sides of the regular polygons are 8 and 10.
