Step-by-step explanation:
2sin(x)cos(x) - sin(x) + 2cos(x)-1= 0
<=> sinx( 2cosx -1) + ( 2cosx -1) =0
<=> (sinx +1) + ( 2cosx-1)=0
<=> sinx=-1 or cosx= 1/2
+) sinx=1 => x= pi/2 + k×2pi
+)cosx=1/2 => x= pi/3+ k×2pi or x=-pi/3 + k×2pi
x€ [0,2pi] => x= pi/2, pi/3.
Answer:
4ab and 3ab
Step-by-step explanation:
4<em>ab</em> and 3<em>ab</em> because they have the same variables <em>a</em> and <em>b</em>
128/6 to the nearest whole number = 21
21(6) = 126
128 - 126 = 2oz
Multiply 12 slices by 2/3:
12 x 2/3 = (12 x 2) /3 = 24/3 = 8
The answer is 8
Your solution would be x<25
