Answer:
52 Sides
Step-by-step explanation:
Octagons have 8 sides so 3 x 8 = 24
Pentagons have 5 sides so 4 x 5 = 20
Trapezoids have 4 sides so 2 x 4 = 8
Add it all up and it equals 52 sides in total
Answer:3.63
Step-by-step explanation:because if we divide 18.15 by 5 is equal 3.63.
Answer:
Geometric
Step-by-step explanation:
It has a consistent multiple-factor by which it increases (8).
The correct answer is: [B]: "Difference of Cubes".
<span>__________________________________________________________
Explanation:
__________________________________________________________
Note that the equation/identity for the "difference of cubes" is expressed as:
___________________________________________________</span><span>_______
" a</span>³ − b³ = (a − b)(a² + ab + b²) " ;
<span>__________________________________________________________
Note the given equation: " 19 = 27 </span>− 8 " ; → (which is true).
__________________________________________________________
The "right hand side" of this equation:
→ " 27 − 8 " ; contains two numbers:
→ "27" and "8" ; both of which are "cubes" ;
→ that is: ∛27 = 3 ; ↔ 3³ = 3 * 3 * 3 = 9 * 3 = 27 ; <u><em>and</em></u>:
∛ 8 = 2 ; ↔ 2³ = 2 * 2 * 2 = 4 * 2 = 8 ;
→ <u>AND:</u> "8" is being <u>SUBTRACTED</u> from "27" ;
→ (hence, the "difference of squares" polynomial identity);
So: given: " 19 = 27 − 8 " ;
→ Rewrite as:
" 19 = 3³ − 2³ " ;
_______________________________________________________
Now, consider the identity equation for the "difference of squares":
→ " a³ − b³ = (a − b)(a² + ab + b²) " ;
_______________________________________________________
Take: " 19 = 3³ − 2³ " ;
and rewrite as:
→ 3³ − 2³ = 19 ;
So: (a³ − b³) = 3³ − 2³ ;
a = 3 ; b = 2 ;
___________________________________________________________
Plug in these values:
" a³ − b³ = (a − b)(a² + ab + b²) " ;
→ 3³ − 2³ ≟ [3 − 2) [ 3² + (3*2) + 2² ] ≟ 19 ? ;
→ 27 − 8 ≟ (1) (9 + 6 + 4) ≟ 19 ? ;
→ 19 ≟ (1) (15 + 4) ≟ 19 ? ;
→ 19 ≟ (1) (19) ≟ 19 ? ;
→ 19 ≟ 19 ≟ 19 ? ;
→ 19 = 19 = 19 ! Yes!
