Please tell me what to put down I’m desperate

the 2nd one

Step-by-step explanation:

the first one would cost 30$ after 4 books

10+(5*4)

5*4 = 20

10+20 =30

the 2nd one would cost 24$ after 4 books

16+(2*4)

2*4= 8

16+8=24

f(x)=2/3x+4/3 is the answer because is whose power in the senate is equal to the power of the speaker of the house?

step-by-step explanation:

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
