Answer:
B) 30
Step-by-step explanation:
The interquartile range in 100 to 130.
130-100=30
Distribute on the left
-4x+6=2x
Get x onto one side. Add 4x to both sides
6=6x
Divide both sides by 6
1=x
Final answer: x=1
The correct answer is A. x=22
Since the angles of a rectangle are right angles (90 degrees) you would set it up as 90=5x-20. Then combine like terms and solve the equation. (If you need me to show you how step by step tell me)
