Answer:
-2(-2) + (12-9) = 2 + 9 + -2(-2)
Step-by-step explanation:
Since I cannot draw a number line here, imagine ten jumps below 0 and 25 jumps above 0. To find the distance between -10 and 25, we add the numbers together, ignoring the negative sign.
= 10 + 25
= 35 distance
ANSWER: The distance between -10 and 25 is (D) 35.
Hope this helps! :)
The domain is all real numbers
The range is -4
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 )
