Well i think is better expressed if x^2=9.then x=3, that will be better expressed. Now the converse if clearly false, since if x^2<span>=9</span> it is possible that <span>x=−3. I hope this is useful for you</span>
This problem is half understanding the question and half just plugging in numbers.
Understanding the Question:So its saying that n = whole number bigger than one, making n = 2, 3, 4, 5, etc.
Now try plugging any number n into the

equation. Let's use 2 to make it simple. If you plug in 2, you get:

Remember that the subscripts (the small numbers in the corner) are simply the term number.

is term 1,

is term 2, etc. The equation is saying that "term 2 = 4 times term 1."
If you keep plugging in random numbers for n, you'll see that the equation basically says, "a term = 4 times the term right before it." That makes it easy to plug and chug to get our answer.
Plugging and Chugging
Now we understand the question is asking for the first 4 terms, and each term is 4 times the last term. You're told that term 1,

= 6. That makes the next four terms:
Term 2

Term 3

Term 4

Your first 4 terms are 4, 24, 96, and 384.

Answer: A) F
Answer:

Step-by-step explanation:
<u>Given: </u>
line y=3x-1
point (-3,0)
<u>Write:</u> equation of the line that is perpendicular to the given and passes through the point (-3,0)
<u>Solution:</u>
The slope of the given line is 
If
is the slope of perpendicular line, then

So, the equation of the needed line is 
Find b. This line passes through the point (-3,0), so its coordinates satisfy the equation:

Answer:
C) If the area of a square is an odd perfect square, the perimeter of the square will be even.
