Answer:
Find the smallest multiple the denominators have in common
30
Expand each fraction so that the denominators are 30
![\frac{8}{30} + \frac{- 5}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B30%7D%20%2B%20%5Cfrac%7B-%205%7D%7B30%7D)
Add or subtract the numerators and keep the same denominator
![\frac{8- 5}{30}](https://tex.z-dn.net/?f=%5Cfrac%7B8-%205%7D%7B30%7D)
Simplify
![\frac{1}{10}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B10%7D)
46 because 8-3 equals 5 then 5 times 5 equals 25 to then add 11 to finally subtract 66-20 which equals 46
Answer:
The lines are not perpendicular
Step-by-step explanation:
m1=1/2
m2=2
m1*m2=1/2*2=1
Lines are perpendicular when m1 * m2 = -1 because m1 * m2 = 1 these lines are not perpendicular
