Answer:479001600
Step-by-step explanation:
12 factorial is 12 * 11 * 10 ..... all the way to one
A way to do it by hand is
12 * 1
11 * 2
10 * 3
9 * 4
8 * 5
7 * 6
stop here because 6 * 7 and 5 *8 are already listed
This gives you 6 products then multiply those 6 products by pairs which gives you three pairs which gives you three products then compute a pair then multiply by last product.
Easy math but a lot of written work
9/4 + 3/4 = 12/4 divide by 4 and the answer is 1/3.
Answer:
x + 4
Step-by-step explanation:
(x - 9)(x + 4)
FOIL
x^2 + 4x - 9x - 36 = x^2 - 5x - 36
