The salaries, in thousands of dollars, of all individuals employed at an oceanic cleanup company, are depicted in the boxplot below: What is the interquartile range (IQR) of the salaries? (4 points)

20
40
60
120

step-by-step explanation:

we are given

since, we have to isolate x on anyone side

so, we can move all x terms on one side

subtract both sides by 2x

add both sides by 9

divide both sides by 4

we get

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
