Answer:
108.43°
Step-by-step explanation:
I graphed this expression on the graph below and found the direction angle of 108.43°.
Add 7 to both sides
3x + 12 = 7x
Subtract 3x
12 = 4x
Divide by 4
x = 3
2/9 = 0.2222 or 0.22
3/9 = 0.3333 or 0.33
4/9 = 0.4444 or 0.44
1000/20 is the same as 100/2(you just removed a 0 from both of them)
10/2=5 add a 0
50
First, let's review what the "factorial operator" ! means.
5! = 5*4*3*2*1.
3! = 3*2*1
7! = 7*6*5*4*3*2*1
Then:
7! 7*6*5*4*3*2*1 7*6*5*4 5040
----- = ----------------------- = ------------- = ----------- = 5040 (answer)
3! 3*2*1 1 1
