Answer:
3072
Step-by-step explanation:
<u>General form of a geometric sequence</u>:

where:
is the nth term- a is the first term
- r is the common ratio
Given values:
- first term, a = 3
- common ratio, r = 4
Substitute the given values into the formula to create an <u>equation for the nth term</u>:

To find the 6th term, substitute n = 6 into the equation:




Therefore, the 6th term of a geometric sequence whose 1st term is 3 and whose common ratio is 4 is 3072.

Answer:
21, 28, 36
Step-by-step explanation:
1 + 2 = 3
3 + 3 = 6
6 + 4 = 10
10 + 5 = 15
Next three terms,
15 + 6 = 21
21 + 7 = 28
28 + 8 = 36.

Answer: x+4</h3>
This is because the given expression factors to (x+4)(x+4), which condenses to (x+4)^2.
To factor, think of two numbers that A) multiply to 16, and B) add to 8. Those values would be 4 and 4
4+4 = 8
4*4 = 16
So that's how we end up with (x+4)(x+4). You can use the FOIL rule to expand that out and get x^2+8x+16 again to help verify you have the correct factorization.
All i know is that 1 is the fourth option and 3 is the last option. I would assume 2 is the first option, 4 is the second option, 5 is the fifth option, and 6 is the third option, but be sure to check yourself. I hope this helps!
