12 people fit comfortably in a 4 feet by 6 feet area. use this value to estimate the side of a crowd that is 15 feet deep on one side of the street along a 4 mile section of a parade route

4 x 6 = 24 square feet

24/12 = 2

 so 1 person for every 2 square feet

1 mile - 5280 feet

4 x 5280 = 21120

21120 x 15 = 316800 square feet

316800/2 = 158,400 people

question is incomplete.

(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
