Answer:
This is not a proportion
Step-by-step explanation:
Set up a proportion
9/6 = 2/1
Check with cross products
9*1 = 6*2
9 = 12
This is not true so they are not proportional
Hey!~
I believe the correct answer is C, a postulate .
Hope this helps and have a great day!

Answer:
Step-by-step explanation:
<u><em>Let's check it using Pythagorean Theorem:</em></u>
Where c is the longest sides, a and b are rest of the 2 sides
1) 9 , 40 , 46
=>
=> 
=> 2116 = 81 + 1600
=> 2116 ≠ 1681
So, this is not a Pythagorean Triplet
2) 16, 30 and 34
=>
=> 
=> 1156 = 256 + 900
=> 1156 = 1156
No need to check more as we've found the one which is not a Pythagorean Triplet.
Answer: the fourth option (5p - 2)(5p + 2) (5p - 2i) (5p + 2i)
Explanation:
1) Express the given expression as the difference of two squares:
625p⁴ - 16 = (25p²)² - 4²
2) Factor as the product of a sum times its difference:
(25p²)² - 4² = (25p² - 4) (25p² + 4)
3) Factor each binomial (again square of a difference and sum times its difference):
25p² - 4 = (5p)² - 2² = (5p - 2)(5p + 2)
25p² + 4 = (5p)² - (2i)² = (5p - 2i)(5p + 2i)
4) Therefore, the 4 factors are:
(5p - 2)(5p + 2) (5p - 2i) (5p + 2i)
