It is irrational because it does not repeat a pattern nor does it stop.
Answer:
X=75
Y=110
Step-by-step explanation:
A straight line is 180, so add the equations that make a line and set them equal to 180
x+20+x+10=180
Combine like terms
2x+30=180
Subtract 30 from both sides
2x=150
Divide by 2
X=75
Same for y
y+y-40=180
2y-40=180
Add 40 to both sides
2y=220
Divide by 2
Y=110
The polynomial is not factorable with rational numbers
C) x+3
first one factors to (x+3)(x-3)
second factors to (x+3)(x-2)
5 is the difference.
Note: Minuend - Subtrahend = Difference
