Answer:
Step-by-step explanation:
Since we want to know the actual number of feet, we can write the proportion with that in the numerator.

The real caboose is 42 1/4 feet long.
1.
1.2 x^4 ( 4 x² + 3 x + 1 ) = 4.8 x^6 + 3.6 x^5 + 1.2 x^4
2.
( 4 x - 3 ) ( 2 x² - 7 x + 1 ) = 8 x³ - 28 x² + 4 x - 6 x² + 21 x - 3 =
= 8 x³ - 34 x² + 25 x - 3
3.
( x² + 4 x - 3 ) ( 2 x² + x + 6 ) =
= 2 x^4 + x³ + 6 x² + 8 x³ + 4 x² + 24 x - 6 x² - 3 x - 18 =
= 2 x^4 + 9 x³ + 4 x² + 21 x - 18
