ValentinkaMS [17]

Answer:

3x^11+9x^7+5x^3-x+4

Step-by-step explanation:

A polynomial written in decreasing order is a polynomial that starts with terms with the highest degree and ends with terms to the lowest degree.

First find the decreasing order of the answer:

5x^3-x+9x^7+4+3x^11

3x^11+9x^7+5x^3-x+4

The answer should be this, but I couldn't find a match for it in the answer box.

Charlotte walks home from school every day at a rate of
Anna [14]

Answer:

Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.

Step-by-step explanation:

Since Charlotte walks home from school every day at a rate of 4 miles per hour and it takes her 30-minutes to reach home, while her brother, Noah, runs home from the same school every day at a rate of 6 miles per hour, to determine how many fewer minutes does it take Noah than Charlotte to reach home from school each day the following calculation must be performed:

Charlotte:

4 mph = 4/60 = 0.0666 miles per minute

0.0666 x 30 = 2 miles

So the distance from the school to her house is 2 miles

Noah:

6/60 = 0.1 mile per minute

2 / 0.1 = 20

Thus, Noah takes 20 minutes to get to his house, that is, 10 minutes less than Charlotte.
