Answer: 20
Step-by-step explanation:
2^2=4
5*2=10
2^2 and 5 would be multiplied
Answer:
12
Step-by-step explanation:
sum of all angles of triangle =180
3x-12+2x+11x=180
16x-12=180
16x=192
x=12
a) (f+g)(x) = f(x) + g(x) = -4x + 5x = x
b) -9(x) = -9x? I have no idea what this means.
c) (f o g)(x) = (f(g(x)) = f(5x) = -4 (5x) = -20x
There are 6 letters in the word "autumn" so
6! = 6*5*4*3*2*1 = 720
represents the number of ways to arrange the letters (order matters)
Note how there are two letter "u"s here which can't be told apart. If we could tell them apart, then the answer would be 720. However, we can't tell them apart. So we're doubly counting things. To undo this, we divide by 2
720/2 = 360

Final Answer: 360
