Answer:
The solve of this equation is X = 4,06
Step-by-step explanation:
To solve this formula:
2 ( X² - 16) = 1
You must use the distributive law of multiplication, thus:
2X² - (16×2) = 1
2X² - 32 = 1
2X² = 1 + 32
X² = 33/2
X² = 16,5
X = √16,5
X ≈ 4,06
Thus, the solution of this equation is:
<em>X ≈ 4,06</em>

Answer:
an = 39 +4(n -1)
Step-by-step explanation:
The formula for the general term of an arithmetic sequence is ...
an = a1 +d(n -1)
Here, the sequence has first term a1 = 39 and common difference d = 43-39 = 4. So, the general term is ...
an = 39 +4(n -1)
I'm not 100% sure, but I'm pretty sure its 11 and 13
Answer: 7
Step-by-step explanation:
denotes the intersection of A and C, or in other words, how many elements are shared between them.
The number of elements is 2 + 5 = 7
