Answer:
<em>3.9 kg</em>
Step-by-step explanation:
total mass = (number of nails) * (mass of one nail)
total mass = 750 * 5.2 * 10^(-3) kg
total mass = 750 * 5.2 * 10^(-3) kg
total mass = 750 * 0.0052 kg
total mass = 3.9 kg
The 9-sided polygon will have a central angle between the vertex and the center of one side of 360°/(2*9) = 20°. Then the apothem is
a = (6 in/2)*cot(20°) ≈ 8.242432 in
The perimeter is 9*6 in = 54 in, so the area is
A = (1/2)Pa = (1/2)*(54 in)*(8.242432 in) ≈ 222.5 in²
Answer:
+ 3
+ 2x
Step-by-step explanation:
x(x^2 + x + 2x + 2)
x ( x^2 + 3x + 2)
