Answer:
C
Step-by-step explanation:
Using sum/difference to product identity
• sin x - sin y = 2 cos() sin (
)
with x = 4Θ and y = 2Θ
Then
sin(4Θ) - sin(2Θ)
= 2 cos() sin(
)
= 2cos(3Θ)sinΘ → C
Find the product. Simplify your answer. (m–4)(2m+2)

Step-by-step explanation:
For a given perimeter, the area will be maximized when all the sides are the same length, which makes it actually a square. A square is still a rectangle, though! So, if you know the perimeter, divide it by four to determine the length of each side. Then multiply the length times the width to get the area.
