A decagon has 10 sides. If the polygon is symmetrical, the angle of rotation is given by the following equation:

360 / (number of sides)

Therefore,

360 = 10 = 36.

The interior angles are determined by the following equation:

180 - (angle of rotation)

Therefore,

180 - 36 = 144

The answer is A.

(2x^3)^2 x 6x^2 <br><br> (2m^0 x 5m)^2 x 5m^2

Nana76 [90]

Answer:

$\large\boxed{(2x^3)^2\times6x^2=24x^8}$

Step-by-step explanation:

$(2x^3)^2\times6x^2\qquad\text{use}\ (ab)^n=a^nb^n\ \text{and}\ (a^n)^m=a^{nm}\\\\=2^2(x^3)^2\times6x^2=4x^6\times6x^2=(4\times6)(x^6x^2)\qquad\text{use}\ a^n\cdot a^m=a^{n+m}\\\\=24x^{6+2}=24x^8$
