It's already a square; we don't need to add anything to complete the square.

That's a vertex at x = -1. The corresponding y is y=0.
Answer: Vertex at (-1,0)
As for the other questions cut off there, the axis is the vertical line x = -1 and the range is y ≥ 0.
The ratio of cm to mi is 1/30, and we are looking for x/110. Since 1/30 = x/110, 30x=110.
x = 110/30 = 11/3 = 3.7 cm
Diameter = 6, so length of diagonal = 6
a² + b² = c²
a = x, b = x, and c = 6
x² + x² = 6²
2x² = 36
x² = 18
x = √18
x ≈ 4.2426
x ≈ 4.2 in.
Hope this helps you!
Have an amazing day :)
Step-by-step explanation:
Difference of Squares: a² - b² = (a + b)(a - b)
(x² - 16) / (x - 4)
= [(x + 4)(x - 4)] / (x - 4)
= x + 4, where x =/= 4.
