Answer:
AB = 15
Step-by-step explanation:
Since AD and DC are congruent point D lies on the axis of AC
the axis of a segment divides it in two congruent segments, so AB congruent to BC
5x = 4x + 3
x = 3
AB = 5 * 3 = 15
Answer:
72 square units
Step-by-step explanation:
area of a paralellogram = bh
Base = 6
Height = 12
6 x 12 = 72 square units
Y = mx + n
m = Slope
To two lines be perpendicular to each other the slopes need to meet the condition: ma x mb = -1
y = 2x + 5
ma = 2
D: y = -1/2x + 5
mb = -1/2
ma x mb = -1
2 x -1/2 = -1
2/1 x -1/2 = -1
-2/2 = -1
-1 = -1
It's true.
Answer: D.
