Answer:
-24a² - 42a - 28
Simplified form = 12a² + 21a + 14
Step-by-step explanation:
-4(7 + 3a) - 6a(4a - 5) (distribute -4)
-28 - 12a -6a(4a - 5) (distribute -6a)
-28 - 12a -24a² - 30a (collect like terms)
-24a² - 42a - 28
We can simplify
-24a² - 42a - 28 (divide -2)
12a² + 21a + 14

Answer:
Step-by-step explanation:
Sin(theta) = opposite/hypotenuse
Sin(41 deg) = 2.5/x
Xsin(41) = 2.5
X = 2.5/sin(41)
X = 3.8
Tan 2x = 2 tan x / (1-tan^2x)
hence, tan 2x = 1
2x = pi
x = pi/2.
