Answer:

3x + 8 is equal to 14 when x = 2.

Step-by-step explanation:

To evaluate the expression 3x + 8 when x = 2, we simply subsititute the value of x into the expression. We can write this expression as the function:

f(x) = 3x + 8

And we can evaluate the function when x = 2 by simply plugging in the value 2 for x:

f(x) = 3x + 8

f(2) = 3(2) + 8

f(2) = 6 + 8

f(2) = 14

Hence, the expression 3x + 8 is equal to 14 when x = 2.

Cheers.

Answer:

B. 4√3

Step-by-step explanation:

$\sin \: 60 \degree = \frac{x}{8} \\ \\ \therefore \: \frac{ \sqrt{3} }{2} = \frac{x}{8} \\ \\ \therefore \: x = \frac{8 \times \sqrt{3} }{2} \\ \\ \therefore \: x = 4 \times \sqrt{3}\\ \\ \huge \purple{ \boxed{ \therefore \: x = 4 \sqrt{3} }}\\$
