Answer:
Step-by-step explanation:
hello :
sin x + 2 sin x cosx = 0 equivalent to : sinx(1+2cosx) =0
sinx=0 means : general solution is : x= kπ....k in Z
1+2cosx=0 means : cosx= -1/2 general solution is : x= ±π/6+kπ...k in Z
Answer:
Step-by-step explanation:
10 x 3 = $30
10 x 4 = $12
$30 + $12 = $42 in think thats the answer i havent been to school in a while
<span>V - E + F = 2
30 - 60 + F = 2
- 30 + F = 2
F = 32
Answer: 32 faces</span>
