Answer:
0
Step-by-step explanation:
Simplify the following:
a - a
Hint: | Look for the difference of two identical terms.
a - a = 0:
Answer: 0
6x^2+12x=0 Factor out the greatest common factor which is 6x
6x(x+2)=0
So the there are two solutions, when x=0 and x=-2
The points are, (0,0) and (-2,0)
And they expressed it as {0, -2}
There are 12 possible combinations because you can use each slice of pizza with a different drink

Answer:
75.96 Degrees
Step-by-step explanation:
Use the trigonometric functions of Sine Cosine and Tangent
(SOH CAH TOA)
The unknown angle is near the adjacent side of 2 and the opposite side of 8
Therefore you use the Tangent function
However, since it's the angle that needs to be found, you need to use Arc Tangent (The inverse operation)
Unknown Angle = ArcTan (8 / 2)
Unknown Angle = 75.96 Degrees
Note: ArcTan is just Tan to the power of -1
On my calculator I have to click shift then click the tan function to access this it may be different on yours
