Answer:
20
Step-by-step explanation:
20 percent of 40 is 5
so 20 is d answer
(x² -5x+4) / ,(x-1). ,=. (,x-1)(x,-4) ,/ (x-1)
= (x-4)
1st slope is -1/3. 2nd slope is 6
slope is same in parallel lines so not parallel
slopes are negative reciprocals in perpendicular lines so they aren't perpendicular
they are called oblique
-4^4= -4*-4*-4*-4
-4*-4=16
16*-4=-64
-64*-4= 256
Final answer: 256
