Answer:
See below.
Step-by-step explanation:
x^2 + 2 = 3^2/3 + 3^-2/3
x^2 = 3^2/3 + 3^-2/3 - 2
x = √(3^2/3 + 3^-2/3 - 2)
x = 0.748888296
Substitute for x in 3x^3 + 9x - 8:
3( 0.748888296)^3 + 9( 0.748888296) - 8 = 0.
So it is proved.

Step-by-step explanation:
Annual depreciation expenses is
[Equipment cost-residual value]÷estimated useful life
Annual depreciation expenses
(20,500−2,500)÷4=4,500
Accumulated depreciation at the end of 2 years I
4,500×2=9,000
Book value at the end of 2 years is
20,500−9,000=11,500
