Answer: 3

Step-by-step explanation:

Let say x the width of the tank,

x+4 its length,

x+2 its height

Volume=105=x(x+4)(x+2)\\\\P(x)=x^3+6x^2+8x-105=0\\\\105=3*5*7\\\\P(1)\neq 0\\P(-1)\neq 0\\P(3)=0\\\\\begin{array}{|c|cccc|}&x^3&x^2&x&1\\&1&6&8&-105\\x=3&&3&27&105\\----&--&--&--&--\\&1&9&35&0\\\end{array}\\\\\\P(x)=x^3+6x^2+8x-105=(x-3)(x^2+9x+35)\\And \ x^2+9x+35\ is\ not \ factorizable\ (\Delat=9^2-4*35 < 0)\\

<u>width=3</u>

length=3+4=7

height=3+2=5

Your realized income is 2,847.69/month. your fixed expenses are 36% of your monthly income. you decide to save 40% of your discr
Allushta [10]
If you would like to know how much do you save per month, you can calculate this using the following steps:

your expenses: 36% of 2,847.69 = 36% * 2,847.69 = 36/100 * 2,847.69 = 1,025.17
2,847.69 - 1,025.17 = 1,822.52

saving 40% of your discretionary money: 40% of 1,822.52 = 40% * 1,822.52 = 40/100 * 1,822.52 = 729.008 = 729.01

The correct result would be: You can save 729.01 per month.
