1 and 3 have the same angle and 2 and 4 have the same angle. Since we know what 1 is we know what 3 is, add them together then subtract that from 360 = 148. To figure out the angles of 2 and 4 divide 148 by 2 = 74. 1 and 3 are 106 degrees and 2 and 4 are 74 degrees :)
The answer is 10077696
Because you multiply them by 6
We are asked to create a factorable polynomial that has a GCF of 3x. This can be done in many different ways, but we'll use the easiest one. This will be completing the square.
GCF: 3x
Suitable Polynomial: 3x³ + 18x² +27x
Other Expressible Ways:
1) 3x(x² + 6x + 9)
2) 3x(x + 3)²
We got this by creating a perfect trinomial, which is x² + 6x + 9, as it can be factored into the binomial (x + 3)². All we had to do is multiply 3x to x² + 6x + 9 and simplify. Hope this helped!

What is the recursive formula for this geometric sequence 2, -10, 50, -250, .... ?
The recursive formula for this geometric sequence is:
= 2;
= (-5) • ![a_{n-1}](https://tex.z-dn.net/?f=a_%7Bn-1%7D)
Step-by-step explanation:
To find the recursive formula for a geometric sequence:
- Determine if the sequence is geometric (Do you multiply, or divide, the same amount from one term to the next?)
- Find the common ratio. (The number you multiply or divide.)
- Create a recursive formula by stating the first term, and then stating the formula to be the common ratio times the previous term.
The recursive formula is:
= first term;
= r •
, where
is the first term in the sequence
is the term before the nth term - r is the common ratio
∵ The geometric sequence is 2 , -10 , 50 , -250
∴
= 2
- To find r divide the 2nd term by the first term
∵ ![r=\frac{a_{2}}{a_{1}}](https://tex.z-dn.net/?f=r%3D%5Cfrac%7Ba_%7B2%7D%7D%7Ba_%7B1%7D%7D)
∴ ![r=\frac{-10}{2}=-5](https://tex.z-dn.net/?f=r%3D%5Cfrac%7B-10%7D%7B2%7D%3D-5)
- Substitute the values of
and r in the formula above
∴
= 2;
= (-5) • ![a_{n-1}](https://tex.z-dn.net/?f=a_%7Bn-1%7D)
The recursive formula for this geometric sequence is:
= 2;
= (-5) • ![a_{n-1}](https://tex.z-dn.net/?f=a_%7Bn-1%7D)

Answer:
-4y-12+4b
Step-by-step explanation:
<u>Use the </u><u>Distributive Property:</u>
![- 4(y + 3 - b)](https://tex.z-dn.net/?f=%20-%204%28y%20%2B%203%20-%20b%29)
![- 4y - 12 + 4b](https://tex.z-dn.net/?f=%20-%204y%20-%2012%20%2B%204b)
is an equivalent expression.
