You have to know what it is before you solve the problem
P⁴ - 81
p⁴ + 9p² - 9p² - 81
p²(p²) + p²(9) - 9(p²) - 9(9)
p²(p² + 9) - 9(p² + 9)
(p² - 9)(p² + 9)
(p² + 3p - 3p - 9)(p² + 9)
(p(p) + p(3) - 3(p) - 3(3))(p² + 9)
(p(p + 3) - 3(p + 3))(p² + 9)
(p - 3)(p + 3)(p² + 9)
The answer is (3).
Answer:
you multiply by 2 and then you subtract by 5
pls mark me brainliest
Step-by-step explanation:
You are right, it's a reflection and the axis of this reflection is the perpendicular bisector of CC'
b) you could choose :
red, black
black, red
red, red
c) p(black, red) = (6/18)(12/17) = 72/306 = 4/17
