So to write it out using order of operations it would be -7sinx+7sin^2x-(-7cos^2x). This would then equal 7-7sinx which can be simplified to 7(1-sinx). the way you were able to get rid of the cos^2x and the sin^2x is because cos^2x+sin^2x=1.
1 hr = 60 min
671,000,000 / 60 = 11183333.33 miles per minute
having all the necessary or appropriate parts:
50% = 1/2
1/2 of 400 is 200
200 students bring their lunch.
