Measure the lengths of the runways in inches and then times your answer by 700 and then round that answer.
The way I figured this one out was saying that if it takes 2lbs to stretch it to 12 inches and 5lbs to stretch to 18 inches that means that 3 additional pounds = 6 inches. Therefore, each additional pound is 2 inches. We know already that with 2 lbs it was 12 inches in length and we can also say that 2 lbs = 4 inches. So subtract 4 from 12 and you end up with the answer of 8 inches.
Answer:
6n(n³ - 4n² + 3)
Step-by-step explanation:
Given
6
- 24n³ + 18n ← factor out 6n from each term
= 6n(n³ - 4n² + 3) ← which may be factored further if required
2 ↔ exponent
5 ↔ coefficient
7 ↔ constant
x ↔ variable
Hope it helps!
