Each of these roots can be expressed as a binomial:
(x+1)=0, which solves to -1
(x-3)=0, which solves to 3
(x-3i)=0 which solves to 3i
(x+3i)=0, which solves to -3i
There are four roots, so our final equation will have x^4 as the least degree
Multiply them together. I'll multiply the i binomials first:
(x-3i)(x+3i) = x²+3ix-3ix-9i²
x²-9i²
x²+9 [since i²=-1]
Now I'll multiply the first two binomials together:
(x+1)(x-3) = x²-3x+x-3
x²-2x-3
Lastly, we'll multiply the two derived terms together:
(x²+9)(x²-2x-3) [from the binomial, I'll distribute the first term, then the second term, and I'll stack them so we can simply add like terms together]

Step-by-step explanation:
<u>Step 1: Define</u>
x + 3 + 2x = x + 3
<u>Step 2: Solve for </u><em><u>x</u></em>
- Combine like terms: 3x + 3 = x + 3
- Subtract <em>x</em> on both sides: 2x + 3 = 3
- Subtract 3 on both sides: 2x = 0
- Divide 2 on both sides: x = 0

Answer:
The answer should be 9 9/20
Step-by-step explanation:
You need to take the total volume of the regular box and multiply it by the downsize of 3/10 and that leaves you with 9.45.
