Answer:
The answer is option C.
<h3>-6, -5 2/5, -4 1/5</h3>
Step-by-step explanation:
The arithmetic sequence is given by
![A(n) = - 6 + (n - 1)( \frac{1}{5} )](https://tex.z-dn.net/?f=A%28n%29%20%3D%20%20-%206%20%2B%20%28n%20-%201%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
where n is the number of terms
<u>For</u><u> </u><u>the</u><u> first</u><u> </u><u>term</u>
n = 1
So we have
![A(1) = - 6 + (1 - 1)( \frac{1}{5} )](https://tex.z-dn.net/?f=A%281%29%20%3D%20%20-%206%20%2B%20%281%20-%201%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
![= - 6 + (0)( \frac{1}{5} )](https://tex.z-dn.net/?f=%20%3D%20%20-%206%20%2B%20%280%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
![= - 6](https://tex.z-dn.net/?f=%20%3D%20%20-%206)
<u>For</u><u> </u><u>the</u><u> </u><u>fou</u><u>rth</u><u> term</u>
n = 4
![A(4) = - 6 + (4 - 1)( \frac{1}{5} )](https://tex.z-dn.net/?f=A%284%29%20%3D%20%20-%206%20%2B%20%284%20-%201%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
![= - 6 + (3)( \frac{1}{5} )](https://tex.z-dn.net/?f=%20%3D%20%20-%206%20%2B%20%283%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
![= - 5 \frac{2}{5}](https://tex.z-dn.net/?f=%20%3D%20%20-%205%20%5Cfrac%7B2%7D%7B5%7D%20)
<u>For</u><u> </u><u>the</u><u> </u><u>tenth</u><u> </u><u>term</u>
n = 10
![A(10) = - 6 + (10 - 1)( \frac{1}{5} )](https://tex.z-dn.net/?f=A%2810%29%20%3D%20%20-%206%20%2B%20%2810%20-%201%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
![= - 6 + (9)( \frac{1}{5} )](https://tex.z-dn.net/?f=%20%3D%20%20-%206%20%2B%20%289%29%28%20%5Cfrac%7B1%7D%7B5%7D%20%29)
![= - 4 \frac{1}{5}](https://tex.z-dn.net/?f=%20%3D%20%20-%204%20%5Cfrac%7B1%7D%7B5%7D%20)

Answer:
a= 8x+6x+48x+1
Step-by-step explanation:
Area of large rectangle is represented by a
a= 8x+6x+48x+1 - This is expanded form
Can be simplified to a= 62x+1
Y= 3X + 1. Perpendicular means you would change the slope by flipping it and changing the sign. So the slope then becomes 3. Then you use your points to find the y-intercept by filling in the variables. 7=3(2) + B. 7=6 + B. Then subtract 6 from both sides. B=1. Then you just put your problem back into slope intercept form with your new slope and y-intercept. Y=3x + 1.
X^3 - 21x = -20add 20 to both sidesx^3 - 21 x + 20 = 0Rational Root Theorem:Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20------------------------------- Factors of Q (leading Coefficient) = 1
Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1
Of the choices given only the number 1 is a possible root.
the answer will be triangular/
