Notice the picture below
negative angles, are just angles that go "clockwise", namely, the same direction a clock hands move hmmm so.... and one revolution is just 2π
now, you can have angles bigger than 2π of course, by simply keep going around, so, if you go around 3 times on the circle, say "counter-clockwise", or from right-to-left, counter as a clock goes, 3 times or 3 revolutions will give you an angle of 6π, because 2π+2π+2π is 6π
now... say... you have this angle here... let us find another that lands on that same spot
by simply just add 2π to it :)

now, that's a positive one
and

to get more, just keep on subtracting or adding 2π
To find both f(8) and f(-5), we will need to plug in their values for x and solve for each. Then, we can subtract them to find the final answer.
Finding f(8):
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
Finding f(-5):
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
Subtracting f(8) and f(-5):
f(8) - f(-5)
22 - - 17
22 + 17
39
Hope this helps!! :)
Answer:
Option C: 
Step-by-step explanation:
Given the side length of a square is 11 units.
Note that 
Since, length cannot be negative, we can eliminate - 11.
Hence, the length of the side of the square is 11 units =
.
Hence, the answer.
Which expression has the same value as the one below?
i dont kown cause i cant see the choices
47.C
48.B
49.???
50.A
sorry doing something couldn't solve 49 right now
