Answer:
x is 70°
Step-by-step explanation:
80 + 55= 135
180-135 = 45
45 +45 =90
180-90=90
80+80= 160
180-160= 20
20 +90= 110
180-110 = 70
x is 70
Answer:
x+120 , if x < -120
x+12 , if x > -12
x+12 , if x < -12
x+12 , if x = -12
x÷3 , if x > 0
x÷3 , if x < 0
Step-by-step explanation:

Answer:
- 2 x y^2+3 x^2 y -xy
-120
Step-by-step explanation:
xy – 2xy + 3x^2 y — 4x y^2 + 2xy^2
Combine like terms
xy – 2xy + 3x^2 y — 4x y^2 + 2xy^2
- x y+3 x^2 y - 2 x y^2
Let x = 4 y = -2
-(4)(-2) +3(4)^2 (-2) -2(4)(-2)^2
Exponents first
-(4)(-2) +3(16) (-2) -2(4)(4)
Multiply
+8 -96-32
Add and subtract
-120
