Right side of the equation:
cos ( A - B ) - cos ( A + B ) =
= cos A cos B + sin A sin B - ( cos A cos B - sin A sin B ) =
= cos A cos B + sin A sin B - cos A cos B + sin A sin B =
= 2 sin A sin B - left side of the equation ( correct )
Answer:
A
Step-by-step explanation:
Pick a letter that's easy to count. I chose Q, because it has a tail below the baseline that makes them easy to spot.
Not C or D — too many quarters
Not B — too many nickels
It is often easier to find the correct answer choice by eliminating the bad choices, then seeing if what is left is consistent with the problem statement.
Choice A seems to have the right numbers of pennies and dimes (along with quarters and nickels).

Answer:
x = -17
Step-by-step explanation:
15+x = -2
x = -2 -15 (subtracting 15 both sides)
x = -17 Answer

Answer:
.083 is larger.
Step-by-step explanation:
To find out the solution, add a zero to the .08.
.080
.083
As you can see, the 3 is larger than the zero. This concludes with .083 larger than .080.
