1) equation given: 0 = x^2 - 6x + 4
2) transpose 4: - 4 = x^2 - 6x
3) complete squares: - 4 = (x^2 - 6x + 9) - 9
4) transpose -9 and factor the square trinomial x^2 - 6x + 9:
- 4 + 9 = (x - 3)^2
5) combine like terms: 5 = (x - 3)^2
6) take square root on both sides: x - 3 = +/- √5
7) transpose - 3: x = 3 +/- √5
Answer: the two solutions are x = 3 - √5 and x = 3 + √5

Answer: B) 16 cubic meters
Step-by-step explanation:
To find the volume of a rectangular prism like this sandbox, multiply the length, height, and width together. 2*2*4 = 16.
For the first part, it is y < 2x + 2
& the second part is (-1, -2)
