Step-by-step explanation:
m<ABC =3y+5
m<ADC =5y-45
3y+5 = 5y-45
2y = 50
y = 25
.............
m<BCD = 180 - 80 = 100°
Parallel lines have the same slopes and don't intersect. Perpendicular lines have opposite slopes and intersect at right angles. If it is neither, the lines would intersect without right angles.

Answer:
2.25
Step-by-step explanation:
Using synthetic divison (work below)
I found factored it to equal the following:
(x+2)(x-.25)(x-3)
which means that the zeroes are
(-2,0) (.25,0) (3,0)
The distance between the first and second zero are closest and their distance is 2.25
