Answer:

Step-by-step explanation:
we have

Solve for x
Applying difference of squares in the denominator of the second term in the left side

Multiply both sides by (x+3)(x-3)

Apply the distributive property in the left side

Combine like terms left side

Group terms


Divide by 3 both sides

Answer:
4√2
Step-by-step explanation:
If a square has a perimeter of 16, then its side lengths are 4.
Use the pythagorean theorem to find the diagonal.
- 4^2+4^2=c^2
- 16+16=c^2
- 32=c^2
- c=√32
√32 can be simplified to 4√2.

Answers:
- Not geometric
- Geometric
==================================================
Explanation for problem 1
Divide each term over its previous term.
- term2/term1 = 48/60 = 0.8
- term3/term2 = 36/48 = 0.75
We can stop here. The two results 0.8 and 0.75 do not match up, so we don't have a common ratio. Therefore, this sequence is <u>not</u> geometric. A geometric sequence must have each ratio of adjacent terms to be the same value throughout the list of numbers.
Side note: This sequence is arithmetic because we are subtracting the same amount each time (12) to generate each new term.
--------------------------------------
Explanation for problem 2
Like before, we'll divide each term by its previous term.
- term2/term1 = 6/3 = 2
- term3/term2 = 12/6 = 2
- term4/term3 = 24/12 = 2
- term5/term4 = 48/24 = 2
Each ratio found was 2. This is the common ratio and it shows we have a geometric sequence. It indicates that each term is twice that of its previous term. Eg: the jump from 12 to 24 is "times 2".
