Help me is due today. I will give brainliest if you answer first and if it is correct;)

3n + 5

1. Substitute the numbers

3(5) + 5 = 15 + 5 = 20

2. Substitute the second number

3(6) + 5 = 18 + 5 = 23

This is because I realized I got the number of 4 last because I did 1*2 = 2.

Then I did 2*2 = 4.

So you have to multiply by two to get the next number. Or you can put it to the 4th or 5th exponent of 2.

1.  1

2.  1*2 = 2

3.  2*2 = 4

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
