Answer:
<h2><em>
14 x + 11</em></h2>
Step-by-step explanation:
4*(2x - 1) + 3*(2x + 5) =
8x - 4 + 6x + 15 =
14 x + 11
The answer is 6.4 and your welcome
1) cos (150°)=- cos(180°-150°) = - cos(30°) and - cos30° = - √(3) / 2
sin(150°) = sin(180°-150°) =sin30. and sin30° = 1/2
Then : 5/2(cos 150° + i sin 150°) becomes : 5/2{(-√(3) /2 + I (1/2)]
OR 5/4( - √3 + i)
Answer:
27 years
Step-by-step explanation:
Given that :
Adrian's age = 3
Father's age = 34
In how many years will Adrian be twice as young as his father?
Let the number of years = x
2(3 + x) = 34 + x
6 + 2x = 34 + x
2x - x = 34 - 6
x = 28
