Answer:
The answer is 39.2
Step-by-step explanation:
The first thing you want to do is multiply both numbers by them selves like this: 9x8 and 4x8. Then after you do that, add the sum of those equations and you have your answer. Think about it like this, for 8x4, all it is is just 8+8+8+8. If solving it that way is easier for you, go for it! Hope I could help!
I believe to the my mathematical formula that the answer should be 6.3 due to the fact that 48/2 is 24
Answer:
40320 ways
<em></em>
Step-by-step explanation:
Given
Paintings = 8
Required
Determine the number of arrangements
From the question, we understand that the order of arrangement matters;
This implies permutation and is calculated as thus;

In this case,
, because all paintings are hung;
Substitute 8 for n and r, respectively

Evaluate the denominator



<em>Hence, the number of arrangement is 40320 ways</em>
