The slope of line r = 5 and the slope of line s = -5. Are the lines parallel, perpendicular or neither?

Neither, if they are parallel they slope would be the same, and if they were perpendicular one of the slopes would be -1/5 so I am pretty sure it is neither. (I also graphed it and it didn't look perpendicular or parallel)

Step-by-step explanation:

its adding 5.5 each time

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
