Answer:
Two lines that intersect and form right angles are called perpendicular lines. The symbol ⊥ is used to denote perpendicular lines.
Step-by-step explanation:
Since they are intersecting lines, you would equal them to each other.
(5x+4)= (8x-71)
-8x. -8x
-3x + 4 = -71
- 4. -4
-3x = -75
Divide 3x by both sides gets you x = 25
Your answer would be 210.
Hey there! :D
So for this problem, we would do 20+9 x 40 + 7 which equals 1,363.
Hope it helps! :D
