Sin 2 x + 2 sin x = 0
2 sin x cos x + 2 sin x = 0 / : 2
sin x cos x + sin x = 0
sin x ( cos x + 1 ) = 0
sin x = 0, cos x + 1 = 0, cos x = - 1;
Answer:
x = 0, or x = π

Step-by-step explanation:

You have 3*6=18ft of straight line. then you have the circumference of a circle with a radius of 3 which is 9p
So the perimeter is 18+9p=46.27 ft (to the nearest hundredth)
$45!
if u were discounting something, you would do ( .discount amount x original price ) - original amount! you will get a “-“ with the answer, just remove the “-“!!
