Answer:

Step-by-step explanation:

$f(x) = 2x - 1.....(1) \\ g(x) = 3x + 5....(2) \\ plug \: x = 5 \: in \: (2) \\ g(5) = 3 \times 5 + 5 = 15 + 5 = 20 \\ \therefore \: f(g(5)) = 2 \times 20 - 1 = 40 - 1 = 39 \\ \\ \huge \red{ \boxed{\therefore \: f(g(5)) =39}}$

Explanation would be appreciated. i don’t understand

katen-ka-za [31]

Answer:

$28\sqrt{3}$

Step-by-step explanation:

The area of the big triangle is 1/2 b h = 1/2*6*(12^2 = 6^2 + x^2)

that ends up being $\sqrt{108} = 36\sqrt{3}$

the small triangle are needs to be subtracted....

$\frac{\left(4\cdot \:sin\left(90\right)\right)}{sin\left(30\right)}$ that is the length of the unknown side...

1/2 B * h of that triangle get you to $8\sqrt{3}$

just subtract the two areas
