We need to expand the square binomial and then multiply:
<span>3x(x + 3)^2
= 3x(x + 3)</span>(x + 3<span>)
= 3x(x^2 + 6x + 9)
= 3x^3 + 18x^2 + 27x</span>
124.48 because you can just multiply the number by two.
Sum of all exterior angles = 360°
If each angle is 9°,
Number of sides = 360 ÷ 9
Number of sides = 40
