X² - 16x + 17 = 0
x² - 16x + 8² - 8² + 17 = 0
(x - 8)² - 64 + 17 = 0
(x - 8)² - 47 = 0
-----------------------------------------------------------------------------------------
Answer: y = (x - 8)² - 47 (Answer D)

Answer:
The answer to your question is x = 15
Step-by-step explanation:
Use proportions to solve this problem
![\frac{x}{20} = \frac{12}{16}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B20%7D%20%3D%20%5Cfrac%7B12%7D%7B16%7D)
Solve for "x"
x = ![\frac{12(20)}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B12%2820%29%7D%7B16%7D)
Simplification
x = ![\frac{240}{16}](https://tex.z-dn.net/?f=%5Cfrac%7B240%7D%7B16%7D)
Result
x = 15

Answer:
D. 48 in.^2
Step-by-step explanation:
Sides DE and AB are corresponding, and the triangles are similar.
linear scale factor = k = AB/DE = 12/60 = 1/5
area square factor = k^2 = (1/5)^2 = 1/25
area of ABC = area of DEF * area scale factor = 1200 sq in * 1/25
area of ABC = 48 sq in
Answer: D. 48 in.^2
