Answer:
3a+6
Step-by-step explanation:
a+a+a=1a+1a+1a=3a
2+2+2=6

The way to solve the question is by dividing 2 and 32 = 16
Answer:
7 and 5
Step-by-step explanation:
they have variables with them
Answer:
x axis
Step-by-step explanation:
We know the x value stays the same. If you were to graph the line y=3 and y=-3, you would see that it is a reflection over the x axis.
To answer this question, you can use the values of the unit circle to figure out the angle measurement. Since the cosine is the x value of the circle, we can see that at 45°<span>, the x value is √2/2.
So the missing angle should be 45°</span>
