Factor x^2 + 2x - 15.

a) (x - 5)(x + 3)

b) (x - 5)(x - 3)

c) (x + 5)(x + 3)

d) (x + 5)(x - 3)

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

the ratio of balloons to tables is 5: 2 and the constant variation is 5.

the equation is y=5x
