Step-by-step explanation:
You'll want to first simplify the expression

.
To do that, first distribute the

:


From there, you may just combine like terms:




Answer:
D. 4t - 10
Area of an equilateral triangle is

, where s is length of a side; we have s = 2 + 4 + 2 = 8 mm; then area is

;
Area of a semi-circle = (1/2)π

, where r is the radius of circle; r = 4/2 = 2 mm; then area is 2π;
The shaded area is
![16 \sqrt{3} - 2π = 2( [tex]8 \sqrt{3}](https://tex.z-dn.net/?f=16%20%5Csqrt%7B3%7D%20-%202%CF%80%20%3D%202%28%20%5Btex%5D8%20%5Csqrt%7B3%7D%20)
- π );
Answer: The probability is 1/6 - 16.67%
