For all the questions, we will be using the FOIL pattern.
1. (x+3)(x-3)(3x+2)
(x^2-3x+3x-9)(3x+2)
(x^2-9)(3x+2)
3x^3+2x^2-27x-18
2. (2x+1)(x-2)(x+3)
(2x^2-4x+x-2)(x+3)
(2x^2-3x-2)(x+3)
2x^3+3x^2-11x-6
3. (x-3)(2x+1)(3x-2)
(2x^2+x-6x-3)(3x-2)
(2x^2-5x-3)(3x-2)
6x^3-19x^2+x+6
Hope this helped!

I'm going to simp. them one by one
- <span>(x+3)(x-3)(3x+2)
- (x</span>²-9)(3x+2)
<span>- (x</span>³+2x²-27x-18)
<span>-x</span>³-2x²+27x+18
<span>
- (2x+1)(x-2)(x+3)
- (2x</span>²-4x+x-2)(x+3)
<span>- (2x</span>²-3x-2)(x+3)
<span>-  [x(2x</span>²-3x-2)+3(2x²-3x-2)]
<span>- (2x</span>³-3x²-2x)+(6x²-9x-6)
<span>- (2x</span>³+3x²-11x-6)    (combined like terms)
<span>-2x</span>³-3x²+11x+6<span>

- (x-3)(2x+1)(3x-2)
- (2x</span>²+x-6x-3)(3x-2)
- (2x²-5x-3)(3x-2)
- [3x(2x²-5x-3)-2(2x²-5x-3)]
- (6x³-15x²-9x)+(4x²+10x+6)
- (6x³-11x²+x+6)
-6x³+11x²-x-6

All you need w/ these problems is a bit of patience and to know the foil-ing process and distribution. :D

The radius of a nitrogen atom is 5.8*10^-11 meters, and the radius of a beryllium atom is 1.12*10^-10 meters. Which atom has a l
Burka [1]
Nitrogen Radius = 5.8 x 10⁻¹¹ m

Beryllium Radius = 1.12 x 10⁻¹⁰ m

Let's find the quotient of N/Be :

(5.8x10⁻¹¹)/(1.12x10⁻¹⁰). But 10⁻¹¹/10⁻¹⁰ = 10⁽⁻¹¹⁺¹⁰⁾ = 10⁻¹ = 1/10 = 0.1

→ (5.8/1.12).(0.1) = 0.58/1.12 = 0.518.

Conclusion: the radius of Be is almost double than the radius of N
