Answer:
see explanation
Step-by-step explanation:
This is a difference of squares and factors in general as
a² - b² = (a - b)(a + b)
16
= ( 4
)² ⇒ a = 4![x^{4}](https://tex.z-dn.net/?f=x%5E%7B4%7D)
1 = 1² ⇒ b = 1
Hence
16
- 1
= (4
)² - 1²
= (4
- 1)(4
+ 1)
4
- 1 ← is also a difference of squares and factors as
(2x² - 1)(2x² + 1)
Thus
16
- 1
= (2x² - 1)(2x² + 1)(4
+ 1 )
Answer:
Your answer is B
Step-by-step explanation:
Count down 4 points from B on the graph and count 1 over until you reach C which is down 4 over 1
Answer:
34
Step-by-step explanation:
In PEMDAS, you do parenthesis first. So you do 14/2 (7) and 18+5 (23).
Now that the parenthesis are gone, adding is the only thing we can do, so you add 7, 23, and 4 to get 34.
B would be your answer:))
