X² - 16xy + 64y²
= x² - 2*8xy + (8y)²
= (x - 8y)²

Answer:
$84
Step-by-step explanation:
1. If 20% is marked off, then you are selling it for 80%.
2. 455 * 80% = 364
3. Since you are finding the cost markup from 280, then 364-280=84
M + 12 = 10
take away 12 from both sides.
m = -2
Answer:
16
Step-by-step explanation:
plug in -20 for x to get |-20+4|
that is |-16| but the absolute value of it is 16
