Question Help 2.4.PS-9 The equation P=5s represents the perimeter P of a regular pentagon with side length s. What is the perime

Serjik [45]

Answer:

Perimeter = 15 cm

Step-by-step explanation:

The equation P=5s represents the perimeter P of a regular pentagon with side length s.

We need to find the perimeter of a regular pentagon with side length of 3 cm.

To find it, put s = 3 cm in the given equation.

P = 5(3) cm

= 15 cm

Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.

What is the factored form of 8x^24-27y^6

zalisa [80]

Factoring: $8x^{24}-27y^6$

Theory : A difference of two perfect cubes, $a^3-b^3$ can be factored into

$(a-b)*(a^2+ab+b^2)$

Proof : $(a-b)*(a^2+ab+b^2)=$

$a^3+a^2b+ab^2-ba^2-b^2a-b^3=$

$a^3+(a^2b-ba^2)+(ab^2-b^2a)-b^3=$

$a^3+0+0+b^3=$

$a^3+b^3$

Check : 8 is the cube of 2

Check : 27 is the cube of 3

Check : $x^{24}$ is the cube of $x^8$

Check : $y^6$ is the cube of $y^2$

Factorization is :

$(2x^8 - 3y^2)*(4x^{16} + 6x^8y^2 + 9y^4)$
