First, distribute the minus sign across the second set. So you have:
x - y + 1 - x - y + 1
Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2
So we have -2y+2
Hope that helps.
Answer:
-1
Explanation:
3π / 4 = (3*180) / 4 = 135 degrees
Since 135 is in the 2nd quadrant, therefore:
tan (135) = - tan (45) = -1
cot θ = 1/tanθ
Therefore:
cot (3π / 4) = 1/tan(3π / 4)
cot(3π / 4) = -1
Hope this helps :)

Step-by-step explanation:
The area of the circle is 50.24 square units. To get the area of the circle you have to multiply π × r². When doing the conversion it would be Area = 3.14 × 4 × 4 = 50.24
