It's 4. The factors of 12 are: 1,2,3,4,6,12. The factors of 20 are: 1,2,4,5,10,20.
Answer:
968
Step-by-step explanation:
Current office length = 22
22 * 22 = 484
484 * 2 = 968
Answer: 
Step-by-step explanation:
Knowing the information provided in the exercise, you need to find the Least Common Multiple (L.C.M) in order to solve it.
You can follow these steps:
1- You must descompose 2, 5 and 8 into their prime factors:

2- And finally, you must multiply the commons and non commons with the highest exponent:

Therefore, the answer is: 
The answer would be 54, because A= PQ over 2 = 9 x 12 over 2 = 54
Answer:
f(2) = 0
Step-by-step explanation:
Evaluate the function at x = 2.
f(x) = -3x^2 + 6x
f(2) = -3(2^2) + 6 * 2
f(2) = -3(4) + 12
f(2) = 0
