Answer:
(x + 2)(x² - 2x +4)
Step-by-step explanation:
The sum of cubes factors as ...
(a³ +b³) = (a +b)(a² -ab +b²)
Here, you have a=x, b=2, so the factorization is ...
x³ +8 = (x +2)(x² -2x +4) . . . . . . matches the first selection

Triangle 2, blue
Triangle 3, green
Triangle 4, red
Interesting problem.
First - let's figure cost of each uniform at purchase.
3,000/40 = $75 each
When some uniforms were returned at $40 - there was a difference of $35 in what they paid and what they rec'd in return. ($75 - 35 = $40)
See picture below for a geometric view.
Let x = height of building
We use basic trigonometry to find x.
The tangent function = opposite side of right triangle OVER adjacent side of right triangle.
tan(2°) = x/1
Solve for x.
After multiplying both sides by 1 (here 1 represents 1 mile), we get
tan(2°) = x.
We now use the calculator to find x.
In fact, you can take it from here. Use your calculator.
