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]

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

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.

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.

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
