Hello there!
The formula is
N! = n(n -1)(n - 2)
Now all we have to do is replace N by 4
N! = 4(4-1)(4-2)
= (4)(3)(4-2)
= (12)(2)
= 24
Here you go, the answer is : 24
I hope this answer help! Good luck with your studies.
Everything that is not 4/9
I equals 70 grams cup because
Perimeter (P) = 2L + x
4900 = 2L + x ⇒ 4900 - x = 2L ⇒ 
= L
Area (A) = L · x
A = () (x)
= 
To make a fraction into simplest form you have to find the greatest common factor. In this case it is 5. So then you divide both the numerator and the denominator by the greatest common factor of 5.
15÷5=3
100÷5=20
There is no factors that go into both 3 and 20 so simplest form is 3/20.
