Answer:
46
Step-by-step explanation:
Multiply the two by both numbers inside the parenthesis
2 x 6 = 12 2 x 15 =30
Add those numbers together
12 + 30 = 42
Then add the remaining four to that number
4 + 42
Base area = 6 ( 1/2 x 6 x 5.2) = 93.6 cm²
Volume = base area x height = 93.6 x 17 = 1591.2cm ³

Answer: Volume = 1591.2 cm³

Answer:
- A) A = 27.3°, B = 56.1°, C = 96.6°
Step-by-step explanation:
<u>Use the Law of Cosines:</u>
- A = arccos [(b² + c² - a²)/(2bc)] = arccos [(13.2² + 15.8² - 7.3²)/(2*13.2*15.8)] = 27.3°
- B = arccos [(a² + c² - b²)/(2ac)] = arccos [(7.3² + 15.8² - 13.2²)/(2*7.3*15.8)] = 56.1°
- C = 180° - (A + B) = 180° - (27.3° + 56.1°) = 96.6°
Correct choice is A.
if you are trying to work out -3/4 - (-1/4 - 1/2) then the answer is 0
