Step-by-step explanation:
In order to write any polynomial in standard form, we need to check the degree of each term, then write each term in order of degree, from highest to lowest, left to right.
The given polynomial is

Here, the combine degree of x and y in each term is 4.
If we arrange the terms according to the degree of x, then

If we arrange the terms according to the degree of y, then

Hence, the correct option is A.
The hypotenuse of the way that they have taken is equal to 2 miles. Jogging this distance with a rate of 5 miles per hour will take Jesse 0.4 hours. Further, for Mark to be back to the starting point, the total distance covered is 2.75. Dividing the distance by 12 miles per hour, it will take Mark only 0.23 hours. Thus, Mark will reach the initial point first.
