If the product of two integers is zero, then which of the following MUST be true? A) Both of the Integers are zero
B) At least one of the integers is zero
C) The sum of the two integers is zero
D) The difference of the two integers is zero

B

Step-by-step explanation:

Anything times zero is zero, so any whole number can be the second one so long as the first is 0.

The sum doesnt have to equal zero because non zero numbers multiplied by zero still equal zero.

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

just sum

10 + 10 = 20
