Answer:
y=4x+6
Step-by-step explanation:
Answer:
4.41
Step-by-step explanation:
you multiply 2.1 times 2.1
All internal angles in a quadrilateral add to 360
so
x+110+110+70=360
x+290=360
minus 290 both sides
x=70 degrees
Answer:
So -1-9= -10
And if x =4 then 2(4)-4y=20
Y= -3
Step-by-step explanation:
2(4)-4y=20
8-4y=20
-4y=12
y=-3
