Step-by-step explanation:
if you arrange values in numeric order you will see the middle value, median, is 16
the median of the lower half of data (first quartile) is 8
the median of the upper half of data (third quartile) is 23
interquartile range = 3rd quartile minus 1st quartile

11x+20
Distribute:
=3x+(4)(2x)+(4)(5)
=3x+8x+20
Combine Like Terms:
=(3x+8x)+(20)
=11x+20
-13y-3
(-4y - 1) + (-9y -2)
remove parenthesis
-4y - 1 + -9y -2
combine like terms
-13y - 1 - 2
now we subtract -1 -2 = -3 so
-13y- 3
