Answer:
use formula of equilateral triangle = roots 3/4 a square.
Answer:
-4 < -13(a+6)-17
-4<-13a+(-78)-17
-4<-13a+(-95)
-4<-13a-95
91<-13a
-91>13a
-7>a
Step-by-step explanation:
Answer:
2.5 inches
Step-by-step explanation:
(1/4) x 10 = 2.5
or .25 x 10 = 2.5
Parallel lines have the same slopes (but different y intercepts). Parallel lines never cross. Parallel lines are the same distance from each other no matter where you are on either line. Think of it like a pair of perfectly straight railroad tracks.
-------------------------------------------------------------------------------------
Perpendicular lines cross at one point. The two lines form a 90 degree angle. The two slopes multiply to -1, which is another way of saying that the slopes are negative reciprocals of one another. For example, a line with a slope of 2/3 and another line with a slope of -3/2 has these two values multiply to -1; therefore showing they are perpendicular lines.
