The distance is 14 miles; the first jogger finishes in two hours, while the slower jogger is still 12 miles in. The slower jogger then reaches the end of 14 miles twenty minutes later, because 6mph also means 2 miles per twenty minutes.
Answer:
A
Step-by-step explanation:
Given
(3x² - 11x - 4) - (2x² - x - 6)
Distribute both parenthesis, noting the second is distributed by - 1
= 3x² - 11x - 4 - 2x² + x + 6 ← collect like terms
= x² - 10x + 2 ← this is a quadratic with 3 terms, thus trinomial → A
2.4•10^-10
the dot is the multiplication symbol and the -10 is the exponent
