Give the most general solutions to the equation 2sin x cos x - sin(2x)cos(2x)=0

part I:
Simplify the first expression using the double-angle identity for sine

Part II:
factor the left side of the equation

Part III:
solve the factored equation

multiply length by height. multiply the length by the height, and then double the product. work out 10 x 10 results = 100 square inches, then work out 100 x 2 = 200. the answer is 200 square inches.

step-by-step explanation:

6 adults and 9 children went.

a + c = 15

12a + 9c = 153

12(6) + 9(9) = 153

72 + 81 = 153

ill answer if you tell me the qestion
