Requires 3 digits; whole number

189

Step-by-step explanation:

2/9 of the school = 42 sixth graders

2/9 / 2 = 1/9

42 / 2 = 21

1/9 = 21

21 x 9

20 x 9 = 180

1 x 9 = 9

180 + 9 = 189

9/9 of the school = 189 students

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )
