They are not parallel because the slopes are different (slope of 4 and slope of 0.25)
Neither are they perpendicular. If they were then m1*m2 ( the product of their slopes) would be -1 ). The product of these slopes = 4*0.25 = 1)
So choice A is the correct one.
Answer is C:9
12^9/12^5 = 12^4

Answer:
1
Step-by-step explanation:
15,580.84 rounded to the nearest 10 thousand is 20,000
P = √ab
p² = ab
p²/b = a
a = p²/b
